I have approx 20 1 yr old hens that I thought were molting through the winter, seeing as that they were were completely bald backed. A neighbor who is an oldtimer said that the particularly bald ones were "getting the roosters attention" and that's why they were bald. Any advice? It has been snowing and I hate for them to be so exposed! The shy hens have full feathers so I am thinking he may be right....
