I have two Chickens that are about 9months old. One has lost all her toes over the winter. She seems to be happy and getting along fine. She cannot get up into the coop and has made a nest on the ground where she lays her eggs. She also can't roost. Is this a problem? These are my first chickens so any adivice is welcome. Also any thought on how I should prepare for next winter? Michigan can be very cold. Thanks.
