my big breed hens wont stop messing with my bantam broody hen

[chickenmama109]

hi. my bantam hen went broody yesterday, im waiting three days to give her fertile eggs just to see if she will stay with it. this is her first time going broody and im afraid the bigger breed hens are going to break her. i was wondering if anyone new of a DIY mixture that can go on her head to put a bad taste in the hens mouth to maybe keep them from pecking her. thanks

You could try separating her from them. I think that may be easier than putting a foul taste on her head. Move her into a new enclosure during the night and she will likely stay broody.
