I have a chick that is approximately 2-3 weeks old making a gasping motion. She is sneezing a bit, and just opening her beak like she is trying to get more air. She is breathing and peeping, but her peeps are muffled unless I ruffle her up a good bit and then she makes normal level noises. What could be wrong with her? Any home remedies? They are on medicated chick starter and get fresh water constantly. Help please!
