I'm considering getting Dorkings this year, but I have questions first that I hope someone here can help me with.
Is the five-toed-feet gene dominant?
And -- there are another couple of flocks around here who have different owners (who might not be pleased with five-toed-ness,) and all the chickens free range, so if the rooster were to mate a four-toed hen, what is the chance that the chicks would be five-toed/carry the five-toed genes?
Five toed trait is called polydactyl. It is an incomplete dominant trait. When crossing 5 toed and 4 toed birds with each other (sex of each does not matter) in the first generation you will get close to an even mix off offspring with 5 toes on both feet, or 4 toes on both feet, or 5 on one and 4 toes on the other and chicks with a mixture and partial 5 toed with the fifth toe actually branching off the 4th toe. Done this cross many many times. If possible Only keep the 5 toed birds for breeders, however, if crossing the mixed offspring back to homozygous 5 toed parents it is not terribly difficult to get back to all 5 toed birds. Then you just deal with quality of toe arrangement.
