I'm with you. I used to put hens in the "hospital coop" for prolapse or whatever. Not anymore. If it isn't something that is easily taken care of, I've discovered that I usually end up losing them in a few weeks anyway, no matter how hard I try to fix them. So now I make a choice after a day or two (depending on the severity, a prolapse that stays put after 1-2 tries can stay in the hospital coop before I make a decision, chronic problems...
not so much) and just take care of things quickly. I still have tears in my eyes every single time, but I know that they will not suffer. Hugs to you.
