Bantam hen has sour crop. Have been giving her a little scrambled egg with probiotics and water with acv for 2 days. Only seems slightly better. I think I can get hold of some Nystatin...should I give her that? She is more stressed being isolated from the flock, but I don't want to let her eat regular food too soon. I don't think she has an impaction. Her crop is just very soft and mushy. Any advice appreciated!!!
