still looking for the best bantam choice for my young 4H children. we live at 7000 ft. with an average temp of 25-35 degrees in the winter months. we are converting our 4 X 6 greenhouse into the coop using insulated foam board and siding. i know we need to keep the chicks in a brooder for a while before they are able to live in the coop. so my questions are... what breed would be best for our conditions? (preferably bantam because the kids will show them and they are only 9 and 7) and how long should the chicks stay in the brooder? i don't even have chicks yet and i am already a nut. we are a very excited family who knows nothing. any and all advice would be helpful.
