The best thing about broody mama's is you have nothing to do but watch. SHE will do all the work. Make sure the chicks can get to food and water that's your job. Maybe put some chick saver in the water for a couple days to help with the vitamins and minerals they need and as a bonus it will be good for the rest of your flock. Enjoy, broody mamas is the only way I hatch chicks I have an incubator but never use it.
