Hello, I have 2 hens that have no feathers on their backs. Completely bald with not really any sign of any new growth. My coop has had scaly leg mites in the past, could this be the cause? I feel like the mites are relatively controlled. I have a rooster but his spurs are cut. I do not ever see other hens picking feathers. There is no redness, swelling or signs of mites in their feathers. (though i dont for sure know what to look for) The few feathers that surround the bald area look poorly. One, if not both hens are laying eggs or atleast trying to lay eggs. The coop goes down to about -2 celcius at night but we are expecting some colder weather so it might go a bit lower. Will these hens be alright? The hens are confined to the coop in the winter but the door is opened on the nicer days.
