Down to 3 eggs as of this morning. She somehow managed to 'escape'. I'm not even sure how, I haven't found any duck-sized holes. Only thing I can think of is she managed to stretch the alrighty tight bungee cords holding down the tarp through a spot the pallet isn't blocking and pushed her way out, but that'd require a lot of strength...
One of the eggs was eaten. I think by her, considering bill marks on the shell. What a brat. The other 3 are fine and she's sitting on them. I'm thinking 4 was dead but I'll never know.
