They're not really pecking each other, but all 12 of them seem to be interested in pecking the same wall (and a particular spot on the floor too) of their plywood brooder box. I'm a bit afraid they might chip their beaks. It's a rather large box for week old chicks, so I can't imagine space is an issue. I have a red lamp on them at 90 deg, and all of their other eating/drinking/pooping behavior seems quite normal. I'm brand spanking new to this, so if anyone has any experience or advice, I'd rely appreciate it. Thanks!
