I bought 6 three day old chicks @ the feed store yesterday. They are gold sex links & completely adorable. Two of them seem to sleep a lot more than the rest, one of those we think may be dying. It lays down to sleep and only moves when we touch it or the other chicks bump into it. Is this normal, should I be worried and what should I do? I've never started with such young chicks and I'm worried about this little one. If I'm able to post a pic it will be the chick that is towards the top of the picture.
