Your rooster must have been a barred carrying silver and over hens carrying gold.If so then your cockerels will be split for silver and gold.They will throw silver and gold 50/50My autosexing project was stopped. Of course, the last batch of chicks that hatched are all silver and barred (not red and barred like I wanted). I am growing them up and if there happens to be a rooster and some pullets, I might try to breed them together. Otherwise, looks like any pullets from that will go in with my red EE rooster for basic sexlinks. I have a new goal for an autosexing project that will lay blue eggs, it will just be more araucana like. I may have to start a separate thread once I start hatching
to their chicks no matter if these cockerels appear pure for silver.So do not give up there is still hope.I had the same problem.My cuckoo rooster carried silver and I bred him to red/gold hens.I got all light chicks.Some hard to describe from the partridge EE.I picked up a crele rooster at the sale bard and have him over my silver and the two red hens.Try again.
