http://www.khpet.com/thermo-chicken-perch.html I've been researching ways to take the edge off of the combs and wattles of my leghorns this winter, when it gets well below 0F, and stumbled across this. I don't recall seeing it mentioned in here before. Anyone have one? Opinions? I don't think I'd ever try one, but I'm definitely curious about how well they work and the response from the birds.
