Our first time with a broody hen resulted in 5 little chickies. All are doing well at 1.5 weeks. We put the babies and momma in a seperate run that is 4x8. We also have 5 black Ameruacanas that are 17 weeks old and 3 hens that are 29 weeks (like the momma). When can Wilma and her babies be let out of the run for a good stretch and scratch without fear of the other two flocks?
