My 3-year old hen, Dottie, has a big squishy crop. On Tuesday I started her on miconazole 3-day yeast treatment (cut the suppository in thirds and gave her a third 2 x a day) after seeing it recommended on BYC. That first day when I gave it to her I could see the liquid in her throat, there was so much of it. The next morning it seemed slightly better, couldn't see any liquid but her crop was still very big and squishy. She didn't seem to be eating a ton but ate some and passed some poops (looked fairly normal but small, one liquidy one that I saw under her roost). I also tried to massage her crop a little but she really doesn't like to be held so it was tough. Her other symptom is a head twitch, she twitches it side to side every now and then. I have not vomited her because I didn't want to aspirate her and cause more harm. I was able to get her to an avian vet on Thursday, which was the soonest they could get me in. The vet, whose expertise is in parrots and other pet birds, was instantly sure that she had sour crop but she said it was bacterial. I asked how she knew it wasn't yeast and she got a bit snippy, saying she had 24 years of experience and it's almost always bacterial. I'm kicking myself for not questioning more, because I came home and looked at tons of articles online and it seems like they all say it's usually yeast. The vet drained what she could out of the hen's crop with a tube and washed it out with chlorhexidine and then she gave me injectable antibiotics (Ceftiofur) to administer 2 x a day. She also said to put 8 tablespoons (!) of ACV in 1 gallon of water. That seemed like a crazy amount to me so I've done 3 tablespoons instead. I am also really worried there could be a yeast problem so I gave the miconazole again this morning though she missed a dose last night. I also ordered some bird probiotics to give her, they just arrived though so will have to start tomorrow on those. So... long-time chicken people - is this treatment going to help? I'm worried the antibiotics will make yeast go crazy if that is part of the problem. The vet didn't want to do a test on the fluid and seemed quite affronted that I questioned her diagnosis. I fear she may be going by what the problem is usually cause by in parrots rather than in chickens, though I know they do treat a lot of chickens at the clinic, it's just not what she got her education in if that makes sense.
