Pullet is very lethargic and skinny

[Banana01]

I’m almost 100% sure she has sour crop, her crop is mushy and gurgling, and her beak and head smell strongly like yeast. It has already been stated that she is ten months old. She’s on All-Flock pellets. I don’t want to feed her anything because of her crop issue.

Is her crop empty in the morning? If so, that is easier to treat than a gastrointestinal blockage.

It has felt mushy and full since this morning, so it hasn’t emptied yet, unfortunately.
