    Best hatchery for SOP birds?

    Sandhill Preservation has a few breeds which were sourced from SOP flocks. Use discretion.

    Genetic Testing?

    Heterozygous oocyanin can't be 100% differentiated from homozygous based on shell traits, however, a heterozygous hen produces slightly less saturated blue color eggs. I can usually tell a homozygous hen because her eggs are more intense blue. Easiest way is to take a picture with my cellphone...

    Ear Color Genetics

    Thank you Nicalandia, I came here to post that ear color is sex linked. I've seen it in my crosses of Silver Laced Wyandottes with Blue egg laying Brown Leghorns. A rooster with white/red earlobes (meaning heterozygous with 1 white and 1 red gene) may produce only red ear males and only white...

    Hen feathered Roo/Hennie genes

    Hen feathering is from reduced testosterone. It has several negatives including reduced fertility for roosters. Hen feathering is useful for breeds such as laced or special colors where the hen colors are desired. Hen feathering was used in several early breeding efforts such as with Silver...

    Possible breeding program

    For future use, a broody hen won't accept chicks from an incubator until she has clucked to them overnight. Just after dark, put the chicks in a box beside the hen where she can hear them. She will usually accept them the next day.

    Breeding blue egg laying Olandsk Dwarfs?

    For breeding objectives, here are a few things that can help. 1. Blue egg is dominant but a single copy of the gene usually produces lighter blue eggs than 2 copies. With practice, you can select homozygous hens based on eggs they produce. 2. Any trace of porphyrin (brown eggs) in your...

    Chicken combs. How to breed for different types?

    Single comb and pea comb are different alleles of the same gene on chromosome 1. Rose comb is from a combination of the rose comb inversion on chromosome 7 plus single comb on chromosome 1. Rose comb on chromosome 7 plus pea comb on chromosome 1 gives walnut comb. Two versions of rose comb...

    anyone working on a white-egg laying Easter Egger? (or other white-layer cross)

    Most Ameraucana chickens are relatively light weight. A cold tolerant breed generally runs between 7 and 10 pounds. Pea comb, rose comb, cushion comb, and flat rose comb are common on cold tolerant chickens. Yellow legs are an important trait for cold tolerant chickens. White eggs are mostly...

    Silver Laced Wyandottes that lay blue eggs

    I'm getting ready for another year of selection and breeding. My SLW's are laying about 8 eggs per day and should ramp up quite a bit in early February. One desirable trait in SLW is laying even in the coldest weather so long as they have plenty of food. I have a two year old rooster tested...

    Silver Laced Wyandotte question

    Beautiful chickens, comb is not typical rose, appears to be flat rose as typical of Foley's birds.

    Ameraucana genetics question

    She was both rumpless and a white egg layer so two strikes you're out of the breeding pool.

    Ameraucana genetics question

    Some interesting side effects from crossing Silver Laced Wyandotte with blue egg laying Brown Leghorns might be useful. I've had both red ears and white ears with chickens that visually are Silver Laced Wyandotte. I think there is an interaction with egg color as white ears correlate with sky...

    Silver Laced Wyandotte Cockerels, any good?

    Neither of the pictured birds is good enough for serious breeding. A has problems with smuttiness in saddle feathers and pointed lacing. B and C have too much black in hackle feathers. A is the better choice of the pictured birds. One of the issues is from the slow feathering variant in...

    Genetic advantage of single over pea comb

    "Laying eggs in winter in a cold climate doesn't sound like an evolutionary advantage to me" Humans shaped chicken evolution for roughly the last 3500 years. We provided selection pressure to lay eggs in quantities well beyond what jungle fowl lay. We wanted chickens to lay in cold climates...
