Question....what would cause a hen to lose feathers around her throat (right under her beak area)? No other symptoms that I've been able to observe.  I saw one hen the other day who was missing feathers in this area.  Thought it was odd but didn't really get to examine her.  Then today I thought I saw a 2nd hen with the same thing.  Again, not totally sure about what I'm describing here since I didn't get to examine them more closely.
