I have been working to move my hen and 6 chicks out to the shed/coop. They are 6 weeks old now and mom is still actively caring for them. They have been in my basement until now where is gets around 45-50 at night easily. They have been spending days outside in about 45 temps in the sunlight. It is supposed to be 35 tonight. Would you put them out in a draft free safe spot with mom without a light? If I did add a light for tonight, I could only do a 75 watt and I feel a bit uncomfortable about that since all the hay is in this shed--fire hazard! She has raised babies before...very good mom...buff orp. Last time I let her stay broody over the winter!! Oh--and when do they technicial "feather out"?
