I have a new bantam chick that has a full crop all the time, but she isn't growing like the other chicks (I'm comparing her to the other bantam chick we got that was the same size) and she peeps all day unless I hold her. She was very lethargic this morning, and threw up a bit after I massaged her crop. She pooped twice today and I gave her water, but I'm not sure what else I can do, and I'm afraid to feed her. Any help would be appreciated.
