I have 2 Gold Laced Wayandotte eggs I placed in my bantam coops nest box hoping for one of the cochins to brood on. Instead I got an Old English Game Bantam who set on them immediately. I'm shocked they and her egg even fit under her to be honest. Do I leave her to it, or separate her so a larger cochin can possibly take over? I'm mainly uncertain if her considerable size difference might end up a problem later. She's my favorite hen, and a real sweetheart so I'm tempted to just let her be.
