My 7 month old Blue Copper Maran had to have a crop impaction surgically removed. I had hope to clear it myself with some of the remedies on here, however to no avail - so the avian specialist removed lots of impacted grass and some sand 6 days ago. Here crop is healing well, except that I think it is slow now or just really saggy. It gets nice and big during the day (just laying crumble mash, feather fixer, a little yogurt, vits, and antibiotics) and in the morning it is about the size of a small plum - very soft and squishy. I have ordered her a crop bra. She is isolated from the others. My concern is how much to feed her, but without overfeeding her to prevent sour crop? I am giving her 10 ounces a day of laying crumble/feather fixer, and she definitely would eat more if I let her. She is a little underweight, so that's why I added the feather fixer - more protein without being hard to digest. I know that the impaction was not due to worms, egg binding/internal laying, metal/foreign bodies. I know I could still lose her since she could still have the issue that caused the problem in the first place, however vets are not inexpensive so I have to consider that in my decision to provide the best care I can for her now that the immediate problem is handled. Can anyone give me an idea of how much food to provide her with due to her circumstances? Thanks!
