Right now, I have silver, buff and wheaten ameraucana hens mixed together, living with a buff Ameraucana roo. So about half of the eggs that come from their nests will produce full blooded buff Ameraucanas, while the other half will be barnyard mixes. I have a bachelor pad where I have a silver cockerel and a wheaten cockerel living. I kept them for breeding purposes, to mate with their own kind if I ever wanted to so so. The silver and wheaten cockerels do not have any female companionship. Say I wanted to get a few full blooded silver ameraucanas. Obviously I would have to pull my three silver ameraucana hens out of the main ameraucana henhouse and put them in with the silver cockerel. But since this rearrangement would cause big problems in the overall management of my hen compound, I am wondering just how long I would have to relocate these silvers in order for them to produce mostly or completely nothing but fertile silver ameraucana eggs? A week? Two weeks? A month?
