With that small of a flock I wouldn't worry about separating her. Just make sure that you mark the fertile eggs under her so that if they lay in the nest you can remove the extras every day.New chicken keeper needing advice. I have a Broody hen in a nesting box. The coop is raised above ground and only 4 x 4, I'm hoping not to but it is possible to section her off from the other two hens or move them to The enclosed run. Recommendations?
