6+ inches of snow tonight followed by sub zero temps and my girls have decided that NOW is the perfect time to molt. 
(oh and also I am in need of deworming but the dewormer says not to give during a molt as it can interfere with feather production!
)
And this doofus: she has literally no feathers left under her wings or on her butt!

But the consensus seems to be that nobody has had trouble with feathers when deworming during a molt. So I wonder if it's actually that big of a concern. I would be more worried about the worms if my hens had an active infestation.
