K&H Pet Thermo-Chicken Warming Perch, 36”

Maine weather worrier here. Tomorrow night we are supposed to have record lows and I was worrying about my elderly 9yo chicken ladies. We have always let them be all natural, but a predicted -20 below with a windchill of -40+ below, well I felt I needed to help them. After reading the reviews, I see people either loved these or hated them. I just installed them a couple hours ago in preparation for tomorrow night's he** freezing over. I used the recommendation of another person about zip tying them on the existing perch. I also laid it on its side so they have more width to grab on to. Both of these things addresses 2 out of the 3 issues people had. The ladies jumped up on the bar the second I attached it to the perch (it was already past bedtime for them so no coercion was needed). I went back out in an hour and the bar was nice and warm. They were snuggled up on it and when I asked them if they liked it, well, I got the equivalent of a chicken purring. Happy chicken tender here so far. Now to wait and see how the next 48 hours goes as the arctic blast arrives tomorrow. It's only currently 25 degrees (the directions say it will shut off above 35). So far so good. Update: We got the temperatures predicted. Went out and checked on them a few times and all were well. One last adjustment I would recommend, if you attach it on the side, put a shim under the thin end so it will sit level. One had a harder time balancing and had to move her back onto the bar. Wish it had a more grippy surface like it rubberized surface so it wouldn't be as slippery. Overall, it provided the warmth we were looking for.
