My 3 year old bantam araucana rooster had a bout of crop-binding at the end of the summer, which I fixed over a few days with olive oil/bread and crop massage. He then seemed fine, although his molt was taking a long time. Last weekend I noticed he was not well, hunched, ruffled, closing eyes. When I picked him up I was shocked to find that he was just feathers and bones, with a puffed crop. I put him inside in a small dog crate. I've been giving yogurt with probiotics and some papaya enzyme (I read about this on some parrot sites - it's got enzymes that help digestion and might help with crop issues). I've also been carefully massaging the gas out at least three times a day. I've been massaging his crop so often that this morning I noticed I massaged some the feathers off of a section of his crop area. This time it's not bound up - just gassy and not moving things through quickly. But, for the last few mornings, his crop was totally empty and had no gas. The gas just built up during the day. This morning, however, his crop was gassy. I found a website from, Mississippi state that suggests using acidified copper sulfate for sour crop, and I do have some of that, so I am changing tactics and starting him on that today. There is only one vet around here who will see chickens and he is out of town and not available till next week. I didn't want to try a vet earlier this week because the bird was so thin and unwell I thought the stress of moving him would kill him. Now he is cheerful and alert, but not getting any less gassy. And so thin I don't know how he is still alive . I think it's time to make a crop bra, but I don't know how to make one. Any other suggestions to help this bird? Sorry this was so long.
