My friends chickens died from being broody and they didn't even have eggs!
I have read since being on BYC that geese and ducks will starve themselves to death when brooding so I always make sure any of my birds who are brooding get up and out daily. Sometimes they get carried away and don't take care of themselves. . I had a Muscovy this year who started brooding in April I didn't wan any ducklings this year so I took her eggs didn't matter she just kept sitting, I tried taking her out daily and closing up where she was sitting but every evening there'd she go right back to where she had her nest even though I'd go in daily and stir up the bedding This went on everyday from April till about 3 weeks ago. She brooded on nothing. Finally I kicked her out again and this time she quit on her own. started to molt and is looking much better, Brooding is hard on them because they don't take that good of care of themselves eating little so I'd get her off the nest clean out all the old bedding and put down new. I actually broke a broody last year by removing all the old bedding and adding new, she went in to her stall and looked around like Wow where did everything go, and she was done. this girls this year was a big challenge, I just made sure she got out to eat and bathe when I finally figured out she was not going to get off on her own. Please do what ever you need to to get this duck to either quit brooding or at least make sure she gets out daily to eat and bathe and try removing all the old nesting material and adding new this may do it. I'd hate for you to loose her. Some will use a pen with hardware cloth all over with out any bedding to break them for brooding, I don't have anything like that so don't know successful that is with ducks I think it works good with chickens.
