Our hen Chickenny has been acting lethargic, droopy, and slow all day. I noticed this morning that her crop felt 'floppy' and it's quite a bit worse now. I was looking up possible ailments, and I believe it's sour crop. We brought her inside the house a few minutes ago, and tilted her and stroked her crop to get her to throw up. She did- a whole bunch of water with a tiny bit of grass. She also pooped, again, very watery its an off color. Now she's just standing inside- we gave her a bit of plain yogurt mixed with Apple cider vinegar, oyster shell, and a water/ vinegar mix for her to eat/ drink if she chooses. We're plannning to keep her inside tonight. What else should we do?
