Hi, We have four chicks, they're six weeks old. This morning when I went to check on them, my otherwise active and noisy Golden Campine chick was dragging her wings. I think she might have gotten stepped on. At one point when I let them wander around she fell over and seemed unable to get herself upright. I knew they were getting bigger and I'd have to seperate them soon into groups of two. I just didn't think they were this big yet. She's not making her normal sounds, or flapping. She's not pulling her wiings to her, and I was able to fan them out with no problem. She even let me hold her with no protest. She is eating and drinking, and walking around a bit, but she even looks sad...I feel so bad. What do I do? Help!
