Thank you so much for replying! I wonder if I should move the mama hens to their own little places like a dog kennel or pen? They are first time brooders so I don't know if it will throw them off. I did move one hen to another nest when she went broody and climbed in with the first hen and started stealing her eggs. I moved her to another nest box with eggs I had saved up and she did just fine. I just didn't think it all the way through or I would have moved her to a separate place all together when they first went broody.
The best time to try to move them is while they are still on 'fake' eggs, though even if on the real eggs you can try moving them but expect to possibly need to move them back if they freak. It is simpler when they are segregated somehow from the other layers but some hens just don't tolerate being separated.
