I have four 3 year old hens and recently added four more hens to my flock. I bought them at Tractor Supply and made sure that I was getting pullets only. They were all the same age when I bought them and about a month ago I started to notice that one was so so much larger than the others and it’s comb and waddle is a lot bigger and redder. I’m beginning to think that I have a rooster but not sure what to look for. I’ve never had a rooster before. Help please.
