I have a mix of brown egg laying hens that are six weeks old (14 of them). I raised them from day old chicks. Four weeks in the house in a brooder, then the past two weeks they have been in their 3x5 outside coop. It is completely enclosed and has a heat lamp in it. Two days ago I opened their door to the run and moved their food and water to the run also. Within a half hour of opening the door they all came out to the run. That night they were all still in the run right at dark so I picked them all up and put them inside. They stayed there all night. Today they all came out in the morning and have been there all day..Now its dark and they are all laying down under their coop as if they are gonna spend the rest of the night there. It will only get into the 40's tonight so it shouldnt be too cold for them...but should I pick them up and put them in myself every night until they go on their own..or just leave them to decide?
