Chelle - One thing I used to do when I was breeding canaries was to give bad mommas "dummy eggs". They're little plastic eggs that the momma could ignore or brood. If a hen never got broody, there was food additives I could give them that would encourage brooding (hemp seed primarily). I have no idea on chickens/turkeys, though. I suppose that you could use an old L'eggs Egg for a turkey if you could find one.. or a plastic easter egg to start 'em out. That way she's not ruining viable eggs. But a pile of silkies trying to sit on a single turkey egg would be hilarious. Are they able to keep the egg warm enough? I don't know the temp requirements of chickens vs turkeys..
