I was wondering if these three chickens were hens or roosters. I thought all three of them were hens, but I'm not quite sure. They are about a year old. They are just getting out of a molt so they are looking a little rough. The first picture I think is a rooster (but I'm not quite sure). The second looks a little like a hen and rooster so I'm the most confused about that one. In the third picture in the front is the first chicken again then there is another one I'm unsure about behind it. Please help!
