One of my Wellsummers went missing after sleeping in the rafters of the coop. After about 10 days she turned up out side the coop, ate and disappeared. My chickens free range during daylight and I did see her once or twice during the next 10 days. After about 25 days she reappeared with 18 chicks! We moved the chicks and mama into a protected place away from the cat and dog etc. The chicks and mama are doing well but what now? How long do I keep them together? Should I let mama out if she wants and let her come back on her own?
