There is something wrong and I can NOT figure out what is causing it. My girls (3 2 RRI 1 Aust) egg have thin shells and the whites are thin as if the eggs were 'old' . When I hard boil the eggs the white is mushy and makes peeling almost impossible. I feed Dumore from T.S., a few meal worms as treats, 'good' snacks, berries, strawberry pieces, and yogurts almost every day. (Organic plain.) Coops are clean, fresh water always available. I fed some Rooster Booster for a while before I changed the watering system - it helped a little but still not right. ANY ideas appreciated. Thanks !
