Hi, Just adopted 4 6-9 month old birds today. I believe that I have aRIR(maybe mix, maybe pure?), a Dominique, an Australorp mix(welsummer dad?) and a light brahma mix i believe (might be welsummer daddy again as most of her roos were welsummers). I have a question on the brahma mix... it is a big bird... please confirm it is a hen... it is the only one we are questioning right now. Pretty positive the rest are hens.Thank
