Hi, I don't know if I have seen this question before, and am really curious about introducing a rooster in with our young pullets. We have 4 BO's, 4 Americanas, 3 Auricanas, and 1 black/white speckled one that was in with the E Eggers, don't know what breed. Now, if we were to decide to introduce a rooster, what would be the best breed to suit all of the girls? I don't know what effect a certain rooster breed would have on any offspring - size or genetics? it might just be best to have no rooster and not have to worry about it.
