I have 4 ameraucana roosters 1 blue wheaten, 2 wheaten, and 1 white ameraucana. I will be breeding for the best blue egg color I can get in future generations and I have read that the blue egg gene is connected to the comb shape in ameraucana roosters so I was wondering if there are physical indicators I can check on my three roosters to help me advance toward the bluest eggs. I will only be keeping 2 roosters this year and I'd like to keep the best blue egg genes I can but don't have the space to wait to do a test run. I'm not really concerned with the perfect looking chicken at the moment just the egg color. I'm also planing on crossing the white rooster to another melting pot of a chicken breeds I'm working on, all my offspring from this mix have been white so far if I cross them to the white Ameraucana rooster what colors could he ad to the mix, I'm hoping to keep the white plumage trend going but I don't know what color genes are connected to white amerauncana chickens? Thanks in advance to anyone who can offer up some knowledge on this.
