Naturally, it's mostly the Rhode Island Reds. They've been little velociraptors from day one, afraid of nothing. Even a couple of the Cochins do it. They come up behind and all around me and just nip, nip nip! Just today, I've actually taken to *gently* swatting them. We can't be having any of that nonsense around here, this is sort of like a petting zoo situation and at 18 weeks, their bites are starting to hurt.
