Suddenly our chicken coop is full of feathers. It looks like all of our chickens are losing feathers. They are all about 3 months old (all five are EEs) and they still look pretty neat and smooth and I don't see any big bald spots but they are grooming themselves a lot more than usual and our yard looks like someone opened up a feather pillow and shook it all around. Are they molting or getting adult feathers or what? Any ideas? Thanks!!
