I have a 2 and a half month old rooster and it did something interesting yesterday. I have never seen or heard of this before. My rooster tried to mate with my month and a half old chick. He grabbed the chick's neck and tried to do the deed. I don't know why he would do this. When do roosters usually start mating? I have a rooster that is about 5 months and he hasn't done that yet. The other chick was a silkie and is soooo much smaller than the rooster. None of my other roosters that are also 2 and a half months of age have done anything like that either. Does anyone know of anything else like this happening? Does anyone have any idea of why he did that or if it is normal?
