Hi! I'm new from New Brunswick, Canada. We just got are first batch of chicks 2 weeks ago. My chicks are 3 weeks old today. For a few days now, I have one that doesn't seem to be able to stand up for a long period. It eats, drinks, poops, scratches around like they others. But it won't stay up too long. It will even lay on it's stomach to eat and scratch in the wood shavings. It's bright eyed, nothing seems to be wrong with it except the laying around. It's the smallest of all the chicks. It's legs are straight. They other ones don't pick on it etheir. Can you help me? Thanks in advance!! P.S. In the second photo, it's the one on the right.
