I have 7 Black Australorps that will be 6 weeks on Tuesday (my first flock). They’ve been outside in their run all day and seem to be doing great. The temp tonight is supposed to be a low of 56°, do you think it would be okay to leave them in their coop tonight? Up until now they’ve been in my basement which stays a consistent 66° and have shown no interest in being on, under or around the heat plate for a couple of weeks now.
