I thought about moving my 4 wk. old chicks out to the brooder house. It's fully enclosed, but it's still cold here at night. What about installing a heat lamp inside a big dog crate so they can go in and stay warm? I could put their food and water in there so they know it's 'home'. Would they be smart enough to go in there at night? I could shut them in the first night or two... I thought that would also be a safe setup for the light. I could put a strong hanger for the light, and then secure the crate so it couldn't be tipped over accidentally.
