Keep up doing what you are doing for her.Well I brought my sick hen to the vet. Her crop is swollen and they gave her some medicine to stimulate digestion. They also did a blood test and said she is anemic. They don't seem to think she will make it; they think she might have some kind of kidney problem cause she keeps drinking lots of water and not eating much. She has perked up quite a bit after getting the medicine though, so we'll see what happens.
She is young, one of the year old hens I got from @PetRock. Hopefully she pulls through.
Consider it hospice care--but she may make it too.
