My 7 ladies and Roo always marched right into their coop at dusk and we'll before the automatic door closed. Then one or two birds got locked out, then more and now the whole flock won't go in until about 9:30. The coop is clean, lit (lights on from 4 to 10:30), and we'll ventilated. They hang out in the light that comes from my house or in one of the covered runs. What can I do? They are free ranged all day in my yard (tightly fenced with an apron) so they get their fill of foraging. Idea?
