My experiences with chicken wounds is to keep them warm and comfortable for the first few days, shock will kill them, then let it heal, keeping stress down and not messing too much with it as well as feeding and watering them and getting them exercising as tolerated after a few days. I have seen some nasty wounds heal up. In a day or so assess if the leg is broken and see how it's healing. If you feel the chicken is suffering too much I would cull to end it's suffering. With deep wounds I don't try to mess with them nor cover them. Good luck.
I thoroughly cleaned it then rinsed it. I put some pain killer free wound cleaner on it and loosely wrapped it in gawz. I put her in a crate in my house and offered her strawberries and water. She eagerly eat the strawberries. In the morning I will use a medicine plundger to make her drink and I will offer her normal food. Will Vet RX in her water help anything? Thanks!Don't use peroxide as it will bubble healthy tissue as well as damaged, however you could use vaseline or an equivalent and wrap it with gauze, and keep it as clean as possible, oh and warm water will rinse it well for the time being.
