I am thinking of purchasing a CERAMIC HEAT EMITTER NO LIGHT BULB 100 WATT (avail in 60 and 150 wt too) for my coop and use it with a rheostat (sp?) to control the temperature. Any thoughts pro or con? Or if I use a regular heat lamp light bulb, what advice do any of you have for wattage? Is there a difference to the chicken if I use a clear or red bulb? I suppose the reason I am hesitant to use the heat lamp light bulb is the fact the it generally stays on all night and I feel this would affect the laying, and/or brooding hen? Then again, the reasearch I've done on the ceramic (no light) heat bulb, doesn't mention using for poultry, only talks about lizards (yick ) and terrariums. To help Millie out in this cold weather, I placed a small heating pad in the bottom of her nesting box, set on the lowest temperature. It has straw over it, and she has been happily sitting on her eggs. But when, and if the chicks come, I'm going to have to crank up the heat a bit more in there. sigh..so much to learn.. All advice/ideas/comments appreciated. Thanks!
