So I have one hen that always mounts another hen. Always the same one trying to mount the same hen. It’s the 2 gray ones. Is this normal?? Not sure if you can tell the difference in the picture but the instigator is the one with the larger comb. They are about a year and a half old. We’ve never had a rooster so I can’t say I’ve seen the act before (LOL) but it’s def NOT just pecking. Someone please tell me what the heck is going on
