I don't use sutures or glue. If you pull the skin towards the spine and rear of the chicken enough, then it will be offset from the cut in the intercostal muscle. I then put Blu-Kote over the incision, and the bird will hold his wing over it so little if any picking.I've noticed the use of sutures to close up the incision made for caponizing. Can glue be used instead? When I cut open my arm, the glue worked beautifully and quickly.
