Is this the same chick that had a hair hanging out of her mouth a few days ago? Just looked at your other posts. I once pulled a long hair from the mouth of a banty chick and he started gasping for air and trying to clear something. I realized I must have pulled some food out of his crop as I withdrew the hair and I guessed that I blocked with wind pipe. After several attempts to get him to drink...turning him upside down...rubbing his throat I finally put a thin rubber hose down his throat like a feeding tube and aimed for the hole on the left as he was facing me. It was out of pure desperation but it worked. Also as I notice you feed your chicks only cracked corn are you providing them with chick grit? Like I replied yesterday the corn is not suitable feed for your chicks and you should get them proper food but if they have been eating corn they really need grit to process it or could be getting backed up and that may be what you are seeing with this little girl. Hope something here helps
