Okay, I was suspecting something like that because it would account for the breathing thing and excess fluid coming from the chick's beak.
Did you get that coconut oil? It would be good to give the chick half a teaspoon now. Measure out half a teaspoon, and chill it slightly to make the oil solid. Then break off small slivers and slip them into her beak. She'll swallow them. Go slowly so she can swallow before you give her the next sliver, until all one-half teaspoon is in the chick. Very gently, massage the crop to mix the oil with the contents. Don't touch the upper part of the crop. If fluid comes out of her beak, stop. Just do this for a few seconds.
Let her rest. She should produce a good size poop in an hour. If not, give her another half teaspoon of oil.  Keep up the warm sugar water every few hours with the Nutri-drench today.
