One of our Buff Orpingtons came up with a comb injury (all pullets, all 20 weeks), not a terrible one- it's the very tip of the top point on her comb. Prior to Blue Koting the area, the tip was dark and I suspect it will fall off, but I didn't want to provoke any more bleeding. She was shaking her head but we didn't see any other apparent injuries. Unfortunately my camera's SD card is picking right now to refuse to upload a picture. We put some Blue Kote on the affected part with a very small syringe but the others immediately surrounded her and started pecking it, Blue Kote and all. She's currently separated in a big dog crate within the main enclosure with food and water. How long does it take for a comb injury to heal? And is there anything other than a good rinse/Blue Kote that we should do to help her?
