I'm not sure if this I'd the right place to ask this question, but do chickens purr? I was sitting outside with my chicks (about 1 1/2 months old) trying to get them used to being outside. For some reason they hate walking in the grass lol and of course they both immediately jump into my lap and one on each shoulder. After a few minutes of plucking my hair, they both laid down and started making this cooing sound... Is it normal behavior or is it a respiratory problem? I haven't been around chickens since I was a child and really don't know much about them yet. I don't even know what breed they are actually, they were an Easter gift. How do you know what breed they are?
