So this past winter 2 of our roos got a bit of frostbite on the tips of their combs . Everything was fine and they looked to both be healing good till today . Go out to check on them and they both are covered in blood and their combs are still bleeding just a little. Could this be caused by the frostbite or is there something else going on like fighting that i need to keep an eye on? Also what steps should i take to care for them now?
