Crate her tonight when it's time for roosting. No Food/Water all night, check her crop first thing before she has anything to eat/drink.UPDATE: We're back from our trip and Helga seems ok, for now. Still molting, of course, but she's moving around and drinking and eating (or at least appears interested).
But... her crop just now, at 9:30 AM EST feels hard and lumpy! So, what I had been treating as sour crop (which I still believe it was) seemingly turned into an impacted crop! I'll stick some coconut oil in the freezer to begin treating her with (frozen will be much easier to work with!).
Does it often happen that one crop issue morphs into another like this?
Checking at 9:30 in the morning is not going to tell you anything. She's already been eating drinking.
