My poor hens have no beards or muffs, just red wobbly bits under their beaks. I am hoping that this is a result of spring molting and not a permanent condition. Their undersides too have bare patches. Egg production is down, which I thought was because we have had a series of broody hens (when they go broody, they stop laying, even for awhile after they stop sitting the nest). But seeing their naked necks and all the drifting feathers in the coop, perhaps the cause is molting, which also decreases egg production. Time will tell.
