Grrr. I keep trying to move the babies and their nesting box over into the Maternity Ward house (away from the other ducks) but every time I do, Mama acts like they don't exist. She just keeps going back to the same place where the nesting box used to be in the main duck house. She even started settling down in the next closest nesting box to where her was before I moved it.
Oooh, fingers crossed!!! As I'm writing this, one of the babies hopped out of the nest towards her (she was standing right in front of it) and it was like that triggered something in her and she got back in the babies nest! She hasn't quite settled down yet though, but she also hasn't gotten out. If she doesn't accept being in the Maternity Ward house, then we've decided that we will brooder the babies inside. I feel bad about potentially taking her babies when she sat on them so long, but I'm more concerned about the other ducks killing the babies if I let Mama and the babies stay in the main duck house.
