We will be getting some new chicks today, and this will be my second go round raising them. Question: I want to try to mimic how they would be raised "naturally" except I do not have a "broody hen." I was hoping I could have them outside, in a "brooder pen" that is a large wooden crate, that we could attach a heat lamp to. It's actually what I used last year, but it was inside our home. We have a couple of variables that might cause issues. It still gets quite cold sometimes below freezing. (That's the biggest concern). Will they be fine being so young, without a broody hen, being so cold? I am thinking so, because I am getting 20, and they should be able to keep each other warm + the heat lamp. Thoughts?
