I have a new rooster, having had all hens before. He is gentle toward humans, but there are three hens that are clearly at the bottom of the pecking order. When I go into the henhouse, they are always on their roosts, while the rest of the flock are going about their business. I worry that they get enough to eat and drink. I've seen no evidence of violence. Not being in there 100 percent of the time, I have a question: Will the rooster ALWAYS chase them away from the food and water, or is he just making them wait until last? What symptoms of not getting enough should I look for?
