One of my hens has a poopy butt. A few days ago I noticed her crop was swagging and realized she has sour crop. I emptied the crop of liquid and with held food from her. After 24+ hours gave her coconut oil for the yeast. 2 days later her crop was empty of the food except a tiny bit of liquid so yesterday morning I let her back out to eat after giving her more coconut oil for the infection. She filled back up with food and I hoped she'd empty it out last night but she still has some in her crop this morning. The crop is really loose. How long does it take for the crop to go back into shape?
