I got my buff orp and BPR from the local feed. They've been in a brooder with plenty of water and chick starter, a heat lamp, and pine shavings. I've also used some organic food grade DE. Ever since I got them they've been very chirpy, sometimes becoming flighty as if they're panicking. Their poo is also watery. I've heard that this is not normal. Our BPR has a bald spot on its back. I've also noticed that they nibble at the pine shavings and the cardboard. Is there any problem or am I just overreacting? Thank you.
