Hello, I'm completely new to having chickens and eager to learn whatever I can. I have five: two barred rocks, one buff orpington, one australorp and one araucana. Ellen (the australorp) is about seven weeks old and the rest are four+ weeks. The rest treat Ellen like the "mom." I live in the inland NW of Washington. I have a few questions: They're still inside and they do have the heat lamp but mostly they roost on the box edge and the roosting pole we have in the box, not under the lamp. Should we turn the lamp off? It's been a much colder than normal spring. Can we put them into their coop yet? Should I have some sort of light out there? And lastly, do I need to clip one of their wings to prevent them from flying out of the yard? Thanks for all your insights.
