Not sure what's going on with my pullets. I let them out in the mornings around 7- 7:30 in the morning. They stay outside almost a day and it doesn't matter what kind of weather. Saturday and part of Sunday it rained and they didn't go in the coop. It was pretty cold so we have heat lamps in the coop.... we turned them on to help them get warm and dry out. But the last few evenings when I got out to lock them up they wont go in the coop. Any ideas why???
