KDOGG331, I'm Blooie, and I'm guilty of getting the Mama Heating Pad thing spreading like crazy. I can't claim the idea - smarter people than me did it first, like Patrice Lopatin, Beekissed, aart, and CrzyChknLady81, who all blazed the path before me. I was just lucky enough to be the one to put all of the information together in one place, and a lot of very good, very brave people picked it up and ran with it. Sites that talk about raising chicks with Mama Heating Pad, either indoors or out, can be found in the links in my signature, just below. Actually all three links have some information. One is about Scout, the little roo who got frostbitten feet and ended up being my trial-by-fire for the heating pad cave. There is also a link to the Mama Heating Pad thread...a lot to take in there but there is a video on page 4 which shows my chicks using their heating pad cave indoors, and a few pages later the same chicks can be seen on a video using the system outdoors, as well as another batch of chicks yet a few more pages in.
