Received five free mixed breed bantams as my first chickens. Since I also wanted some good egg laying hens, I went out the next day and bought 3 gold sex links and two black Australorp chicks. The bantams were already 2-3 weeks old and were getting their feathers. I do not want any roosters on account of neighbors. One of them concerns me and I'm looking for some help. It's comb is already showing while the others aren't.
