I think one of my girls (6 mos.) has sour crop. This is the second day since I noticed her standing - not moving - not eating. I expressed some white liquid gunk from her crop yesterday. She has been isolated, pooping loose green stool, drinking some water and nibbled some yogurt. I sent down a couple of teaspoons of olive oil this morning and massaged her doughy crop. Tried to gently express more crop contents this morning, but nothing came up - as it so easily did yesterday. Does any kind of poop eliminated an impacted crop? Should I try to administer yogurt with the syringe to get more in her? Should I try to be more persistent with expressing her crop? How much time should I give her between whatever treatments I am giving? I'm going to get the feed store apple cider vinegar today. I have heard about baking soda water or saline flushes of the crop. What do you think? Thanks!
