I noticed the early stages of frostbite on the tips of my RIRs' combs so I took vaseline out to treat their combs as suggested on this site. However, the girls were not happy to have me touching the combs at all. They are fine with stroking their feathers all the way up their necks, but when I got to the comb they would flinch. Is this normal or are other things at play here? Thanks!
