I'm getting very concerned about two-year old Snickers. The rest of the flock began molt in fall and have all completed it. I even put off adding artificial light in the coop where Snickers roosts to give her time to molt, but she never did. Not a single feather. She looks frowzy and really needs a makeover. She has been the only hen to lay uninterrupted through fall to the present. She acts otherwise normal and healthy. Is there some way to trigger molt without getting into drastic inhumane methods?
