Hi Amer, Thanks for the photos although side views, both showed the pattern and the "gold" color of the borderline. From Pinterest, front view showing the color and pattern https://www.pinterest.ph/pin/566679565583342653/ Looking at more pics in the net, there is a lot of variation in the...

Hi Amer, thanks, I also assume the two roos are birchen, but in Wyandottes the e locus allele is partridge. Based on the chicken calculator https://kippenjungle.nl/chickencalculator.html what gene/s would be involved for the expression of black breast feathers with silver white border line...

These two photos are from Pinterest, https://www.pinterest.ph/pin/764204630536098921/ and https://www.pinterest.ph/pin/15129348733581672/ What is the genetics of this lacing- silver white border line around a black feather, opposite/reverse of those in the Silver Sebright and Silver Laced...

Clarification regarding estradiol, the effect of this hormone in sexual maturation only applies to female chickens, pullets. What if you mate a naked neck rooster to a couple of your dual purpose hens and time the hatching of the eggs during the summer to find out if having the naked neck trait...

A hen I purchased consistently (4-5 eggs a week) lays medium sized eggs but once every 3 weeks or once a month she lays a jumbo size double yolk egg. So far this hen has laid 5 double yolk eggs, the latest one was laid March 17, 2024 weighing 91.02 grams. Is it genetic? According to an...

Thanks to everyone for your replies! This is very helpful to know, thanks NatJ, The first and only pure heritage chicken breed that I raised starting as chicks was the Barred Plymouth Rock. Out of 12 chicks only 4 grew to maturity (very delayed egg laying, after 11-12 months; why?), all the...

Can early crowing in cockerels be used as a selective indicator for early maturity; and will the daughters inherit this early maturity and lay eggs earlier? If early crowing is a sign of early maturity, will his mature body weight/size be smaller than normal?

Hi Nic, please help identify the genotype. planning to purchase this asil rooster, seller's photo. He is S/S ilver, Co or Db if birchen included, correct? can the e-locus be identified if duckwing, wheaten, partridge or birchen? Thanks. The tail color is a mystery to me what gene would cause...

Thank You father God Lord Jesus for answering my prayers, I know this chicken breeding project is Your will, Your plan for me, based from what has been happening, including this "revelation" of breeding based on a tropically / environmentally adapted mitochondrial DNA. Thank You also that here...

"Egg laying trait is a Polygenic trait. So males transfer their sex linked genes(likely 2) to their doughters. Now I calculate that the total genes involved is about 20 since the reciprocal cross difference is only 10%" Thank you Nic, this is critically important for me to know and i'm glad...

because of natural selection i'm assuming that the mitochondrial DNA of the native naked neck hen would have less deleterious mutations if any compared to those of production type layer or heritage hens so If i want to pass on the mtDNA of the mother native naked neck hen to future generations...
