Ok so I have this white muscovy hen, she is a horrible, horrible, horrible broody. I have had her for the past 2 years, she has gone broody 2 or 3 times a summer, all of them were fails and I blamed myself. Well this time I had everything set up perfect, I had her in a massive dog crate with food and water and a nesting area, she had a clutch of 16 eggs and everything was going well. I assumed that she was getting off to poop but then when I came in one morning the nest and eggs were covered in a ton of disgusting diarrhea! I cleaned off the eggs and started to force her off the nest to poop once a day. This was not enough, she ended up pooping on the eggs again a week later 
So I bumped it up to twice a day! I also added a few rouen eggs to the nest because I doubted the muscovies were still alive. She did break a few eggs during the time on the nest and she ate them. Fast forward to a few days ago and I candle the eggs, they were starting to internally pip, surprisingly. I woke up the next morning to find a dead rouen duckling in a bloody cracked egg, I assumed that she squashed it by accident. Then this morning there was a few external pips, I filled up the her water and feed and came back a few hours later to find a bloody dish of water and a dead duckling on the ground, egg shells in the water... It was the egg that had pipped... I snatched the rest of her eggs and took them inside, I have an incubator but I have chicken eggs in there, I put the duck eggs in there but what the heck am I supposed to do about humidity? I have chick eggs on like week 1 and duck eggs that need to be in lock down, I am not going to feed those eggs to the momma duck, what should I set the humidity at?
Edit: the last time this hen was broody I found a hatchling that was forced out of the egg early and across on the other side of the coop, I just thought a rat must have taken an egg and dragged it out there, even though I have no rats... I think I know who really did it now though.
