I have a duck that showed up behind my house a couple of years ago, so we took her in and we think she is probably a wild duck but she wanted to be with our ducks so we took her in. Ever since she has wanted to be a mother 24/7. one year she hatched about 8 ducklings in january! Way to cold for babies, all of them died except for one, which we kept and he was beautiful! he was black but had a shiny green gloss he also had white feathers because his daddy was white but anyway. This duck has also hatched one of our chickens, we named the chicken stuart, she is a very good hen. The other day i found this duck sitting on a huge nest of eggs. So i pulled out all the duck eggs and found that the chickens had laid in her nest as well. There are 5 or 6 chicken eggs in there. We decided that we wanted some more chickens so i'm letting her sit on them. Because our chickens don't want to sit on them this duck is. Has anyone ever had a duck hatch chickens before? She is like a foster mother to them!
