White earlobes have a pink/purple discoloration. We had a drastic temp change this week with it getting very cold for my location (low 20’s at night). Coop is wrapped, etc and hens free range all day outside in the sun (temp gets up to about 40). They are all acting normal, but I am worried this is a sign of cold damage? Has anyone seen this before? It only seems to be on the white egg layer/earlobe hens, which are various ages and breeds, and it is on both sides of their heads, some are worse than others, with some being more on the face area. Any help or wisdom is appreciated.
