No. Never wormed her, but I scooped and examined her poo and don't see anything at all this morning. Quantity was pretty good. It was mostly pretty liquid, with some smallish solid pieces. She hasn't done much today. Sorry, didn't photograph it at the time. My mistake...Has she laid any eggs?
If you get a chance, try to get some poop photos.
I would re-check the crop again. If it's emptying, then she may have other issues going on. I would smell her breath for a few days just to make sure though - sounds odd, but there can be yeast infection without the crop being full.
Have you ever wormed her?
Still no smell from her beak, but I'll check periodically. She hasn't thrown up again as far as I can tell.
She last laid a thin-shelled egg 2 days ago. She is normally my most reliable layer and wouldn't skip more than a single day except during winter.
