They will be fine, forget the heater.I am struggling with the same question. I live in upstate NY and we are starting to get cold, at times this winter, we will be below zero. I have eliminated drafts and insulated the coop and increased ventilation above their heads.
My concern is that my flock is just over 4 months old. They aren't fully grown adults yet. They look fully feathered of course, but we will hit 20º in a couple nights. I have one of those Cozy Coop flat panel heaters ready to install. I am terrified of fire hazards anyway, so I would rather try this instead. I had it on in the house and it actually does warm a bit. Has anyone else tried this product?
Here is the flock, do they look old enough to get through a 20º night?
Thanks!
