Hi all, first time chick raiser. I have 4 barred rock chicks going on to be 5 weeks old that I have in a dog crate in my basement with a heat lamp on. They don't seem overly cold or hot with it. I want to let them outside, but with the cold, I didn't want to risk it. They're now calling for temps to be in the 50s during the day. I have a super tiny coop with a little caged run area that I plan to use to transition them to outside living while I work on the main coop. Would they be okay outside in that small coop during the day at those temps? They're mostly feathered from what I gather, having never raised chicks before. One is a little slow with some fluff still on her head. I read through other threads saying they should be fine at that age, but most were during the warmer months or warmer regions.
