I got a couple of chicks to add to my coop about six months ago. Once they were large enough to go outside, I moved them to a smaller coop alongside my large coop. One found a hole and got eaten. The other has been doing well, but is definitely at the bottom of the pecking order. The past few weeks, it has gotten more colorful, larger, and has a much bigger comb than the other Rhode Island Reds that I have. The tail feathers are turning black and staring to curve downwards. I really believe it is a rooster, but it doesn't crow and is scared of all the other hens. (I have Buff Orpingtons and EasterEggers too.) I have a total of 8 chickens. When can I expect the rooster to crow and mate?
