Hi everyone! I recently purchased a couple of Rhode Island Reds from my local poultry market. I knew before I bought them that one had some sort of problem, as she had a disgusting bum, but that was all I saw that was wrong with her at the time. The next day, I went outside to have a proper look at her in the quarantining pen, and I noticed she had a very large crop, and looked too calm compared to her sister. I wormed the newly purchased birds and powdered them for lice and mites. At the moment the sick girl is in the bathroom out of the wind outside. I though she might have one or both of Sour crop and/ or Vent gleet. She is currently on probiotics and apple cider vinegar, has daily baths in Epsom salt, and is off feed. As a last resort I had to empty her crop (it was actually big as an apple) by flipping her, because she seemed like she couldn't throw up, and I managed to get a lot of fluid out of her. My problem is that I can still feel grain in her crop and shes lost a fare bit of weight. Is there anyone who can give me good advice on treating her? Thanks a lot everyone! love discussing these topics with people loving poultry!
