Thank you, I may just go this for my next chicks. From then on I will be letting the Momma raise the chicksYes, black ceramic bulb lights you see used for lizards. Gives off no light, does not seem to radiate much heat. Use it in my grow out box in the barn where I raise my birds from about three weeks to about eight weeks. Just enough to keep the chill off of them when it drops below 30. Does NOT seem to warm a large area though, only suitable for small number of birds at a time.
