I have a hen with sour crop. I know there are lots of postings about this and I appreciate the info howerver I have some other specific questions please. This started this past Sunday. I have been expressing the liquid twice daily from the crop (morning and evening). I have her inside with me and have been giving her yogurt and ACV. She is pooping some (thank goodness). I have also given her a little mash with the yogurt and was wondering can I give her some cooked rice or something else to eat?? How long does it take to clear this up? And...have I missed anything? Any help/advice would be appreciated. Mis Prissy is about 4 or 5 years old and I have no idea what breed she is.
