This may be a goofy question, but here goes. I have 23 RIR pullets (22 weeks old) and one of them has developed distinctly white ear lobes. These are not pets and are not really handled at all. She appears to be healthy, acts normally, and has started laying (she laid an egg today actually). My question is, could this be a fungal growth that I should check for or do production RIR red pullets from the big hatcheries occasionally have white ear lobes? I have checked the lists of diseases on various sites and really can't find anything that describes this as a symptom of anything fungal or viral.
