We have five RIR chicks, three of which turned out to be roosters. Of the two pullets, one is not maturing and I think we might lose her. Seeing as how we only had two hens, we went ahead and got three four month pullets, two wyandottes and one brahma. We have a brand new hen house that will comfortably fit twelve chickens. My plan is to integrate the two RIR pullets and one of the roosters, ( rehome the other two roosters), but I know we'll need more hens...for the whole rooster to hen ratio thing. Thing is, I just ordered a poultry fence today and suddenly I'm worried the chickens are going to able to fly over it. So...I need more pullets, but I'm going to need a breed that's heavy ( can't fly), is a good layer and can be sexed easily by the hatcheries......because we don't want ANY more Roos. Anyone know what breed that might be?
