We recently introduced our new chicks to our two older chickens. They would run around the yard and see each other, and now they are in the same coop and run. Since we put them together, nothing bad has happened, but the older chickens are very territorial about both feeders. But this morning, when letting them all out of the coop, I noticed one of the little chicks had a little cut on the back of its head. I am pretty sure that it is from an older chicken. It is super minor, but just wanted to know if there is anything I should do about it, or tips to prevent! Thanks!
