My chick is 1 1/2 weeks but had been acting sick since Saturday. It pasted up and I cleaned her off but she started acting sick. She went to a corner by herself and would just sleep. I treated for cocci. on Monday. She eats and drinks but not growing. She follows the other chicks around and tries to get underneath the older 4 week olds. She won't stop "crying." Her rear end is very hard and swollen. Only a small amount of poop is oozing out a couple times a day. I've tried warm water baths, molasses water, vitamins, and belly massage. Nothing seems to be helping. Please let me know what else I can do or if I should just end her misery.
