She's not shivering anymore, and she spent the night in the garage. So should I keep her during the day and at night stick her back in the coop?
I tried to vomit her today, and again she would have none of it. Her crop felt empty as well. She has been eating and drinking and pooping regularly though.
Her crop was completely empty this morning? No pendulous crop? If the crop is completely empty and has gone back to its normal size, then she doesn't have a pendulous crop. Also being empty, there will be nothing to vomit out. She will not need that crop bra.
BUT...it never hurts to have one on hand. If somebody gets a case of sour or slow crop in the future, these things really come in handy.
It sounds like she may not have a crop issue right now as the crop would still be full or at least slow. If you found her in one of the nest boxes shivering, this sounds to me like she is being bullied, she is hiding in there to get away from the others and they have been starving her out of food and water. A few days in the winter without enough to eat and drink, and they get very very cold.
I think you should spend the day getting plenty of food and water in her and you need to figure out what is going on in your coop. You don't always see bullying. The flock can be on their best behavior when you are around, but come a few hours before roosting time when birds should be stuffing their crops full, she may be going hungry. When they get hungry enough, they will eat just about anything including things that are not food, which could answer for her previous crop trouble.
I would get her back out to the coop later today and let her sleep out with the others. If you don't have several food and watering stations, you need to add more, even if you have a small flock. The higher ranking birds can starve out the lower ranking birds to literal death. The bullies can't guard every food and water station, so add a couple more so the lower in the order birds don't have to compete. You can tell if a bird is being bullied by going up at roosting time and feel everybody's crop. If an otherwise healthy bird lower in the rankings bird has an empty crop, she is being run off. Crops should be full at bed time.
Try to figure out who is causing trouble in the coop. Bullying is very common in all flocks. If one is excessively aggressive, you may need to separate them out from the flock for a while or use pinless peepers on them to keep them from being too mean.
Keep us posted!
