I noticed a few days ago that both of my bucks tails' look... abnormal. They almost look like they are chapped, maybe. They are greyer in color than normal. If I hadn't been told yesterday that frostbite is unlikely I would maybe think it was something related to that. Should I be worried or take any action? Also my does seem to be having a different tail issue. They both seem to have scabs on the tips of their tails and one of Bella's seem to have bled a little. Nobody is acting off, and I am not seeing any other symptoms.
