I have 6 hens that are 2 yrs old, 6 hens that are not laying yet and a 2yr old Wyandotte that is broody and her hatch is due in a week. They all free range but I am worried that the other hens may try to hurt the babies. I have the roosters separated from the hens right now and was wondering if I need to set up a 10x10 fence for the new mother and her chicks?
