Hi All! I'm the proud mama of 9 baby chicks that are about 2 weeks old now. We are starting coop constitution this weekend and I'm wondering what you all do with your hens. Our design is loosely following the Wichita Coop. The run will be secured and covered completely. How necessary is it to close the girls into thehenhouse each evening? We arenot always home before dark, and 3 days a week leave before dawn for work. I'm hoping they put themselves to bed and I don't have to lock them up each night. What do you all do?
