Some days I notice that Alex my BR hen has white legs. Some days they turn back to yellow. Is this something to be worried about? Could they just be bleached some how? I know she is not Cuckoo Maran because she does not lay a chocolate egg. She shows no signs of illness. She eats and drinks well. This has been occuring for a good few months now.
