OK. we went out in the henhouse, where half of it is wired off with pultry netting and has had Lucille (11 mo old Buff Orp) with her nest of eggs from 'gamebirdsonly' and I had set up a brooder already, it is 4 feet long, 2 feet wide and 25" tall, and bought a professional brooder element complete with wafer thermostat...all installed it was great, then we moved the brooder element to the incubator which is now full of more eggs !
So, the brooder outside now has a 250-watt red lamp, and Lucille has been placed in one corner, with food and water, and 3 feet square of space under the red lamp.
I have a sensor directly under the light, and another halfway to the nest, and now my cheeky einstein man is hooking up a spy cam so we can watch without running out there and disturbing the hens every ten minutes.
The temperatures I can read outside, still, I have to glove up and put on a coat in my jammies every hour of the night !
We also have a wildlife cam that takes a picture everytime there is movement, but that does not commute to the house, and the spy cam is a direct feed, from radio shack~
