Once becoming beautiful hens, they are devoted to gift you with lots of jumbo brown eggs. Embedded in the Bielefelder DNA is the auto-sexing function; perfect for families that don't want to get emotionally attached and discover they adopted a rooster in disguise. The Bielefelder is commonly referred to as the über-chicken. Their dual purpose utility, huge eggs, auto-sexing function, gentle temperaments, and beautiful feathers make them a top choice in almost every category.

A starter pullet gives families a jump start on chicken ownership, allows families to skip the need to invest in a heated brooder, and there is less wait time for eggs. Selecting a specific hatch date of a starter pullet is your commitment to pick her up within (6) days of order placement on your choice of Saturday between 8am-5pm or Monday between 5pm-6:30pm . Make sure you select the hatch date desired to ensure your starter pullet is the age you want. For further guidance on what age they can begin to be accimated to outside tempatures, read the section on Considerations of Starter Pullets prior to purchasing.

Personality:

These gentle giants are out-going, inquisitive birds that seem more like dogs than chickens. Hens will sing a song letting you know they laid, but other than that; don't make a lot of noise.

History:

Bielefelder hens are quick to mature, weather-proof, auto-sexing chicken with remarkable performance laying large brown eggs. Not only are they cold hardy, they don’t mind the snow and seem to enjoy playing in the rain. The Bielefelder was developed in Bielefeld, Germany in the early 1970s using several breeds of chickens including the cuckoo Malines, Amrock, Wyandotte, and the New Hampshire.

While this age group has a higher sexing accuracy, our female coverage applies to all Starter Pullets sold.

We are proud to offer more flexible and transparent options than the typical feed store or hatchery. Unlike industry standards, which often sell “pullets” with a >10% chance of being roosters and no returns, we provide several sexing choices to best fit your family’s needs.
1. Male (Roosters)
•A cost-effective option for those who welcome a rooster.
•Sold at a lower price point compared to females.
2. Unsexed (Straight Run)
•Chicks are sold without sexing.
•Expect a natural mix of males and females (up to 50% or more roosters).
•Recommended only for families prepared to manage potential roosters.
3. Female Coverage
•Our most popular option for families seeking hens, especially in areas with rooster restrictions.
•We use standard sexing methods where possible (accuracy ranges: as low as 50% for bantams, ~85-90% for most standard breeds, ~95% for auto-sexing breeds).
•If an accidental rooster is identified:
oText us your order number, breed, feather color of the female covered bird purchased that ended up being a rooster.
oWe provide a gift code to apply store credit equal to the original purchase price that may be used to place a new online order. For the store credit to be valid, the bird must be returned in perfect health the same day as new order pick up. Families often use their credit to order more birds or feed. It is common practice to order double the desired number of bantam breeds considering their higher risk of roosters.
oFamilies may also choose to keep the rooster and forfeit the credit.
•Our female coverage pricing reflects our ethical raising of the males left behind each female purchase—we do not cull day-old males.
4. DNA-Sexed Females
•For families wanting true sexing accuracy and peace of mind.
•DNA testing is the only method considered reliable.
•This option is significantly more expensive (typically 3x the cost of female coverage).

Important Notes
•Decision at Purchase: Sexing options must be chosen at the time of order and cannot be changed after fulfillment.
•Accuracy vs. Cost: Each family should balance the financial investment with the level of accuracy desired.
•Informed Choice: We provide detailed breed-specific information so families can make the best decision for their lifestyle.

Marek’s Disease is a viral infection in chickens that can cause tumors, paralysis, and even death. Deciding whether to vaccinate your flock can feel complicated. This guide is designed to help families weigh the pros and cons, consider flock goals, and recognize early signs of Marek’s versus other treatable conditions.

Should You Vaccinate?
Pros of Vaccinating
Protection from paralysis and death: Vaccinated birds rarely die of Marek’s.
Reduced visible outbreaks: Fewer sick birds within the flock.
Peace of mind: Especially valuable for families raising chickens as pets and prioritize survival over eradication of the disease.

Cons of Vaccinating
“Leaky” vaccine: Birds can become carriers for life even if symptoms are hidden and spread the virus to unvaccinated birds.
Masks natural resistance: Survivors in unvaccinated flocks build strong immunity; this benefit is lost in vaccinated-only flocks.
Ongoing dependency: New chicks will need vaccination if introduced into the flock later, or they will remain vulnerable.

Flock Goals & Typical Choices
Pets / Backyard Hobby: Early loss is emotionally difficult → Usually Vaccinate.
Egg Production (family use): Decision varies. Vaccinate to reduce layer loss, or avoid vaccination if preferring to maintain natural resistance.
Self-Sufficiency / Breeding Resilience: Value natural resistance → Often Do Not Vaccinate.
Breed Improvement & Health Integrity: Want genetics unmasked by vaccines → Often Do Not Vaccinate.
Breeding for Profit: Want maximum marketability and survivability → Usually Vaccinate.
Show / Exhibition Birds: Appearance and condition are critical → Usually Vaccinate.
Mixed or Small Hobby Flocks: Flexible; some vaccinate only new chicks or maintain separate lines.

Early Signs of Marek’s Disease
Watch for:
•Reduced activity / reluctance to move
•Ruffled feathers, poor grooming
•Loss of appetite / weight loss
•Pale combs and wattles
•Mild or intermittent lameness
•Paralysis (leg/wing droop) or “gray eye”
Tip: Gradual paralysis affecting multiple birds is a classic Marek’s sign. Sudden illness in just one bird often suggests another cause.

Common Conditions That Mimic Marek’s
Vitamin B2 Deficiency: Curled-toe paralysis in very young chicks; resolves quickly with supplements. Poultry feed is based on the ‘average’ bird. Some require a more individualize diet to thrive. More common in flocks in which too many treats are provided.
Vitamin E/Selenium Deficiency: Incoordination/tremors; corrected with nutrition. Poultry feed is based on the ‘average’ bird. Some require a more individualize diet to thrive. More common in flocks in which too many treats are provided.
Coccidiosis: Depression, bloody/watery droppings; treatable with anticoccidials. Common with pine shaving style brooders, wet runs, and overcrowded conditions.
Botulism: Flaccid paralysis, neck droop; rapid onset after toxin exposure. Occurs when they drink out of metal containers that contain rust.
Injury/Trauma: Isolated limping or wing droop in a single bird.
Feeding to much Garlic: Loose droppings or diarrhea, unusually smelly feces, decreased feed intake, Weight loss over several days, Lethargy or Weakness, Reduced activity or sluggish behavior, Chickens staying in one spot more than usual, Drop in egg production, Garlic-flavored eggs, which may be stronger than desired, Redness or mild swelling in the mouth or crop, Reluctance to eat hard feed.

Managing Different Flock Types
Vaccinated Flocks
•Vaccine must be given at day-old stage.
•Birds need ~7 days to develop immunity; they are vulnerable during this period.
•Do not mix with birds from multiple sources during the vulnerable window.
•Once immunity develops, expect very low Marek’s losses.
Unvaccinated Flocks
•Vigilant observation is critical.
•Isolate sick birds, maintain strict sanitation. Easier to detect and cull as needed.
•Survivors gain lifelong immunity and build genetic resistance.
Mixed Flocks
•If no exposure occurs, differences may never be seen.
•If vaccinated birds shed virus, unvaccinated newcomers may face high mortality.
•Consider keeping vaccinated and unvaccinated birds in separate housing at least 50’ away.

When in Doubt
•Isolate & Sanitize. When in doubt, isolate out! Always separate sick birds and clean equipment.
•Rule out treatable conditions first (coccidiosis, vitamin deficiencies) by providing common vitamin deficiency and coccidiosis treatment. Observe for improvement.
•Marek’s has no cure; supportive care and good nutrition may help survivors.

Nutrition & Stress Management
Strong nutrition and a calm, low-stress environment are essential whether your flock is vaccinated or not. Adequate space, enrichment, and fresh feed/water go a long way in preventing disease complications.

Disclosure Statement
By completing a purchase and accepting chicks at pickup, families acknowledge and agree that:
1.Vaccination is a personal decision based on flock goals and risk tolerance.
2.Regardless of vaccination status, families assume full responsibility for the current and future health of their chicks.
3.Marek’s disease and other illnesses carry inherent risks in poultry keeping, and no guarantee of survival is implied.
4.We provide information to assist decision-making but are not liable for future losses, illness, or health outcomes once chicks leave our care.
Select your preferred hatch date(s) with the following in mind:
•Order at least 1 similar-aged buddy per order.
•If ordering multiple age groups, ensure your setup supports the needs of each group.
•Availability and breed-specific ages are listed on our availability page.

Chicks (1 Day – 4 Weeks Old)
Orders fulfilled with chicks ranging newborn to 4 weeks old based on the already hatched date you select. Chicks up to 7 days apart in age can share a brooder safely. When mixing bantams and standard breeds together, it is best for the bantam to be the same age up to 7 days older than standards based on size differences.
Temperature guidelines:
0–1 week: 95°F
1–2 weeks: 90°F
2–3 weeks: 85°F
3–4 weeks: 80°F
Our digital thermostat brooders simplify temperature management.

Pre-Ordered Chicks:
Age differences of up to a week may occur when pre-ordering multiple breeds.
DNA-sexed chicks will likely be 1–2 weeks old at pick up once lab results are completed.

Starter Pullets (5 – 15 Weeks Old)
Ideal temperatures: 65°F – 70°F, but pullets can acclimate to colder conditions.
Recommend separate coop & run until at least 3 months old or equal size when integrating with existing hens.
Outside acclimation by age:
5–7 weeks: above 60°F
8–10 weeks: above 50°F
11–15 weeks: above 40°F
Colorado Seasonal Guide (Based on Average Day/Night Temps):
April: Safe outside above 60°F; <11 weeks stay in heated coop at night
May: Safe outside above 60°F; <8 weeks stay in heated coop at night
June – August: Safe outside fulltime above 60°F
Sept: Safe outside above 60°F; <8 weeks in heated coop at night
Oct: Safe outside above 60°F; <11 weeks in heated coop at night
Nov: Safe outside above 50°F; <16 weeks in heated coop at night
Dec – Feb: Safe outside above 40°F; <16 weeks in heated coop at night
March: Safe outside above 50°F; <16 weeks in heated coop at night

Integration Tips:
Introduce starter pullets to full-sized hens at 3+ months. Add multiple new pullets at once for easier flock adjustment. Roosting new members at night once existing flock members are sleeping is the smoothest integration method in our experience.

Hens (4+ Months Old)
Provide ample space, predator protection, and opportunities for natural behaviors.
Roost bars: ≥9 inches per hen
Nesting boxes: 1 per 3 hens
Run space: ≥10 sq ft per bird
Extra run space reduces cleaning frequency and stress.
Free-range or movable runs improve welfare.
Feed: ~1 lb/day; never run out of food, grit, or oyster shells.
Gravity-fed feeders/waterers: ≥1 feeder port per 4 birds; clean water is essential.
