Hello knowledgeable duck folks! We have a breeding pair of Cayugas, and a Mallard. The Mallard is broody, and is taking it seriously now. For the last few weeks she would sit on the nest for most of the day, then leave it around 5 and join the other two wandering around the yard, then would go into the duck barn with them at night. In the morning she would rush over to her nest and start the process over. Last night she refused to leave her nest. I put food and water by her, and she ignored it until the other two came over in the morning and started eating it for her. The nest that she's sitting on is not in any enclosure. It's at a corner of our house, so she's protected on two sides. We have a pallet full of hay in the corner but not against the wall, so she's kind of in an "L" shaped area- so if something came at her from one side, she could run the other way. We know we have foxes on our property. We've never seen them at our house, our dog seems to be pretty good at running off deer and foxes and large birds. BUT the dog is inside at night. And since the Mallard is sitting out there all night alone, I'm wondering if there is anything I can do to help protect her? I'd considered a dog house over her, but then there is only one entrance, so if something came at her she wouldn't be able to get away. Any suggestions? We're also trying to figure out if we want to take advantage of her broodiness and stick some fertilized eggs under her. We also have 5 day old ducklings and had considered giving her one to take care of. If we do give her fertilized eggs, then we'll need to get the eggs that are under her out- they're the eggs that were in the nest when we discovered it about two weeks ago so we marked them and left them there, and have just been taking the new eggs out daily. But the old eggs might explode if she's sitting on fertilized eggs until they hatch, right? Thanks for any thoughts!
