Sorry about the weasel attack. Use 1/2 inch hardware cloth to secure your coop doors and windows, since weasels can get in 1 inch chickenwire. In addition to the slightly frostbitten comb which should heal up in a few weeks, he looks to have an ear infection. Get some tweezers, QTips, hydrogen peroxide, and some plain Neosporin or bacitracin ointment, and another pair of hands. They are easier to handle off the roost after dark, but anytime you can catch him would be good. Try to clean the gunk out of his ear with the tweezers and QTips. Flush out the ear canal with 1/2 strength peroxide, and dig a little more. Then fill the ear canal with the ointment. If you have a regular vet who would prescribe some amoxicillin or clavamox, that would help. Sulfa drugs also work, but he may not require the antibiotics once it is cleaned.
