I performed this surgery on my cochin hen. I used dissolving sutures which I got from my vet. First I stitched the crop closed, Then I stiched the outer skin seperately. I applied bacitracin (first aid oinment) to the incision. I gave her water soluable antibiotics for two days (she didn't like it at all). It healed fantastically! She never picked at it at all. I applied the ointment once a day for 3-5 days and it looked great. She never bothered with it. I fed her only soft foods; yogurt, applesauce, scrambled eggs, chick crumbles soaked in milk for a week. She is completly healed and doing great. I also removed the hay I had in their nest boxes. Now only shavings inside and sand and dirt outside. She sat on and hatched eggs a couple months prior to this impaction. I wonder if she was eating the hay the whole time and that is what started all this. Will attach my video.
