I have a stray Muscovy who has made her nest in my horse barn in the hay. This is her 3rd time laying eggs. She just layed her 1st egg and on day 2 she has disappeared. I checked the nest & her 1 egg is gone. I have a trail cam setup and can see a cat messing in the hay. 1 pic shows "Miss Tilly" sitting on her nest and the cat around her in the hay. She's doesn't seem phased. There are several pics with the cat around but not messing with the nest. What could have happened?
