http://www.shopthecoop.com/mm5/merchant.mvc?Screen=PROD&Store_Code=STC&Product_Code=2FP&Category_Code=He I just ordered this and am wondering if anybody has any experience with them (or something like it). I searched through the previous posts, but unless I overlooked something the last discussion of them was 2007ish. I have a (roughly) 4x6 coop for 7 hens, but some of them are molting now and pretty bare in some areas, so I wanted to provide some extra warmth this winter (I haven't needed to in winters past). I'm thinking I'll attach it to the roof, which is at an angle (from roughly 4' at the high end (where the perch is) to about 2' on the low side), so that it's near but not right over top of their perch (if it were right over the perch I think it might be too close to them). I'm terrified to try and do any kind of light heat source, since it's such a small coop that is already filled with birds and shavings, just asking for an accident. I really hope this works. I got the thermostatically controlled outlet as well, so it'll go on at 35 and off at 45.
