@Lacy Duckwing thank you so much for trying to help me
when I gave her last dose of monistat this evening, more yellow stuff came out of her mouth (oh my goodness it smells so bad, it doesn’t leave you). I tried palpating her abdomen but only felt feathers (she is seriously fluffy) but may get a better look tomorrow when I have someone to help me.
The easiest thing to do is to compare her to other hens. Once everyone is on the roost tonight, feel around their breast bones and lower abdomens. The difference, if there is one, will stand out. Hens with ascities (waterbelly) frequently have lost weight - and the breastbone will be more prominent. Whatever the cause- liver failure, heart failure, the beginnings of EYP, the extra fluid takes up space, leaving less room for digestion and stressing the organs further. Those can sometimes be improved by draining them with a needle.
Now- if this is just a crop issue, that's something else all together. It is possible to vomit a hen, you've already done this by accident a couple of times. It does carry the very serious possibility of sending the crop contents down the windpipe, I want to be exceedingly clear about that. Sometimes just expelling the disgusting stuff can help change the tide, then you can feel if there's some obstruction keeping her from digesting food, or some other problem.
This is my "crop bible" that goes over pretty much every possibility in crop issues and what to do about it. https://www.backyardchickens.com/ar...d-sour-crops-prevention-and-treatments.67194/
