One of my Easter Eggers is loosing feathers, especially around neck, and looks like a hot mess. Her comb is lost its red... We've been having a cold snap here in GA (in the 20s at night) but they are copped and we are running a heta lamp to boost the temp in the coop. She's eating and behaving like her normal neurotic self... But this is concerning me. She is 9months old and has been laying since July.
