Broody Muscovy Hatching Question

[hikerchick]

I have a Muscovy who has been sitting on eggs for what seems like forever. Today I turned around and there was an egg in the pen near her that hadn't been there seconds before. It was partially open and there was a duckling beak and head showing.The beak was moving. I picked it up and put it back near her and she immediately tossed it away again. Does anyone know what is going on?

For some unknown reason this thread posted twice.
Could someone remove the duplicate? Thanks!

OK - never mind. The egg is gone and the chick is dead on the ground. I hope the rest of the hatches go better.
