Hey guys. it snowed an awful lot up here in NY. It's the chickies first winter and i have been pretty worried about them. we have a heat lamp set up in the roost, so they dont freeze their butts off at night. but one of my ameraucanas lost her pretty floof around her beak its all naked skin now. it almost happened over night what could this be? my other chicken started losing feather on the back of her head a while ago, but that was from the overexcited rooster. could she be moulting? or could it be something serious..
