Hi all, Brand new to the forums--first time posting. I'm in Massachusetts & I've had my three hens (Barred Rock, Buff Orpington, Rhode Island Red) since the spring. I'd like to get a heated waterer set up for my girls but I'm worried about safety. The hens live in a wooden coop with cedar shavings. I was looking to buy something like this: http://www.flemingoutdoors.com/elhebaforpof.html. I'm concerned, though, that this would be a fire hazard? Or that the hens will burn themselves on the base... Thanks for any advice! J.
