Here goes nothing. Tonight is their first night outside. The ladies are four weeks old. They haven't been spending much time under their heating pad, even with it set on level 1 for the last week. But the room they were in is far from cold. Tonight is supposed to be 38 degrees. I have their MHP in the new coop and it is set on 4. Hopefully it will be enough. They all have a good amount of feathers so they should be fine. Tomorrow I will finish their run so then they can start to spend more time outside during they day as well.
