We got 6 new day-olds last week and they're now 1 week old. At first we planned to set them up in a section of the coop, but space didn't allow that. So they ended up in the workshop which is safe and insulated but not heated. We have a heatlamp over them and put walls up around their brooder to keep the heat in. There is a thermometer in their brooder and it has never gotten warmer than 80F. They don't huddle up a lot except when they're sleepy. They're growing like crazy and are healthy and active. I don't know if there's any long term effects of keeping them cooler than they should be. We are having a very cool spring up here, so maybe that'll work in their favor. What should the outdoor temp be and how old before we take them outside for a bit. Also how old before they go in with the big girls.
