Hi, I'm curious about the way my chickens are treating my barred rock. We had 2 barred rocks, and 5 rhode island reds-- counting the rooster, he's one of the reds. This morning we found one of the barred rocks dead in the yard. We don't know if the dog killed it, or if she found it dead and was playing with it. So I guess we're going to have to put her up. Anyhow, In our coop, there is a 2x4 that goes across one of the walls at an angle for the birds to roost on. When I went out this evening to give them some water, and I noticed that the reds were picking on the rock. They would peck at her till she had to get off the roost. Every time she tried to get back up they would do it all over again. Are they doing this because she's the only one of her kind left, or are they doing it just because?
