Ok so I have a group of small chickens, my silkies, frizzles, ect. well they are all laying fertilized eggs & they lay in the same nest. My frizzles are supposedly great at being broody so my question is at what point should I expect this to happen? there's about 6 eggs in the nest, when should I expect one of them to get in there and stay? and at what point should I just bring the eggs inside if none of them go broody? new at the hatching thing.
