Tonight I noticed one of my silkie chicks is oddly shaped, smaller than the others, and chirps way more than the others. It's hard to explain, but I'll try. All three silkies are the exact same age, three weeks old. It's the blue one I'm worried about. She is eating well, drinking, and pooping. She's oddly shaped though. The only way I can describe it is that she seems to have no neck and only appears to be half a chick. That doesn't make sense, I know, but that's what it looks like. Compared to her brooder-mates, she's missing everything after her legs. Failure to thrive then maybe? When I got them, they were the exact same size. Lastly, the chirping. This just started really bad tonight. Do you think she's in pain?
