Today's the day! We've had an abnormally cold/extended winter in Minnesota but our flock of 4 destroyed their brooder 3 weeks ago. For a while they were in the coop with a temporary heat lamp, but once they got too big to fit underneath it the started to burn some of their tail feathers off trying to stay warm. (Why was it 5F in April?!?)
At any rate, the heat lamp has been removed from the coop for a week and the last 2 nights were below 15F so I've been bringing them inside. Today they're going out for the last time, no nights below 20F in the near future and at this point they're over 6 weeks old and able to handle the cold.
I know they like being in the coop/run more than in the house, so I'm just as happy for them as I am for me...
