My Black Sumatra hen, named Midnight won't stop sitting on eggs that aren't there. She hatched out only one chick and I didn't have time to set up a brood for just one mama and chick. So I took the chick and slid it under anouther hens watch. (This hen went broody the same day as Midnight) It's now been 5 days and she hasn't figured out that there are no eggs where she is sitting. I've even forced her to stay outside by locking her out of the coop for a couple hours during the day. She just won't stop sitting. Does a hen have to finish going through their cycle before they get off? Or does she really belive that there are eggs under her? PS: I even took out the fake ceramic egg.
