I bought six chicks marked as leghorn. 3 of them were definately white leghorns, but these three are completely different. This a first time post for me and my first chickens. As a result I'm not even sure if they are hens. My white leghorn roosters are tall, slim and awesome. One of the three unidentified chickens crows but nothing like my leghorns. Kind of an choke and crow combination. They are all about 5 months old. My leghorn hen is already laying but these three haven't produced. They have tried to mount the leghorn hen at different times (before I moved her). I don't know if this a domanent act or a matting act. If anyone has the patience to help a chicken noob, I'd appreciate it.
