I really don't know about this and I hope somebody can help. I noticed tonight that one and possibly two chicks I have seem to be sick. They are about 2.5 weeks old. They do very little walking around unlike the other 24 who constantly think they're in a foot race from one end of the brooder to the other. However these two seem to do very little other than sit in the shavings and once in a while look around. If somebody comes by and bumps them, they will get up and move; but then flop right back down. There's no pasting up or anything. They both just look like they have no energy to do anything. I'm worried they have something and may effect the other chicks. Any ideas?
