I would separate her into her own area the others can't get to, so she can't be bullied off the nest, and won't get confused about which nest to return to after taking a break. She doesn't need much space while she's brooding so something as simple as a large dog crate (the rectangular black metal ones) with her own feeder, waterer and nest, will be all she needs.Well my broody got bullied off her nest sometime yesterday .... So when I went down to feed them this morning her 4 eggs were ice cold and she was sitting on the decoy broody nest I set up for my other cochin bantam who is thinking about going broody.... I took them upstairs and put them in the incubator. The silkie egg was clear but the Marans eggs are so dark that I can not see into them.... So I'm down from 4 under broody to at least 3 probably 0...... So hard being the lowest chicken in the pecking order.... She just wants to be a mommy poor thing
