I'm new to chickens. I have 5 BOs that are a little over a month old. Today I found one laying in a little pit it had dug in the coop in the shavings. At first I was really worried and thought she was sick or injured, but then she started kicking all the shavings up through her wings. Then one of the roos laid down and joined her! It was really bizarre looking, but also funny and cute. Since two of the them were going at it, I'm guessing they weren't having seizures of anything... Was this just a dust bath?
