Sounds like a 'guard chicken' was the perfect answer for you!Found another good thing for broody hens. My meat birds are laying but they do not sit on eggs so they all freeze and crack. MY egg coop all went for the 1st big molt and nobody was laying . then one a started to lay but my bad golden comets were eating them. I was deciding how to do the mustard egg trick but it was buff orp to the rescue. She sits on them and this am there were 4 eggs. I wont call it broody yet and I don't want to hatch until spring but I hope she continues to sit and keep them from freezing or getting eaten.
