These are out chicks, we've only had them about a week, so they are about that old. One of them is a Bantam that seemed to cheep quite loudly, and someone on here thought it was because she was smaller. Someone else recommended maybe getting another one so she wouldn't be the only little one. I went down to the feed shop today and they had just gotten their new chicks in. I got one, and when I put her in they were immediately curious, but the first Bantam we got seems like it's a little aggressive towards her. It will peck at her beak. The other ones mostly leave her alone. Here's a pick of the new one. I'm pretty sure she's only a few days old as she doesn't have a real feathers like the other ones do.
