they'll be 5 weeks old tomorrow and are about 99.9% feathered out (only a few random downy feathers about the head on 1 or 2 of them). it's been in the mid 80's during the day and in the mid-high 60's at night where we are. they're still inside a box indoors in a room that remains in the high 70's - 80's. i've been turning off the heatlamp during the day. their coop has an indoor section which i was planning on putting bedding in for warmth. it's not really possible for us to run electricity outside. what do you think? can they go out? any tips?
