I ordered 3 more chicks but one came in 2 weeks early and it is too small to go in the 3 chicks that I got that are now almost 3 weeks old. I put the new speckled Sussex chick into a small cage by herself but put it up again the larger cage with the older chicks. Each cage has it's own light. When I first put her in the cage she drank lots and lots of water and then slept for a long time (3 or more hours). I've been checking on her and when she does wake up she seems very wobbly and has not tried to eat or drink anything. It does not appear that she has pooped either. When I got the others last month they were very active and ate everything in sight and hardly ever slept during the day. Should I be worried and is there anything I should be doing?
