I want to place a ceramic heat emmitter in my coop to raise the temp a bit on cold nights. The only problem is that the birds sit on a perch that is about 18 inches below the ceiling. I'm a little worried that they might somehow burn themselves if I put it that close to them - they aren't the brightest girls. I can just see one of them trying to lick it or just get really close to it. I had an iguana for years who never had a problem with it being close, but she was a smart one. Anyone had problems with their flock around one of these?
