HOW OLD ARE MUSCOVY HENS WHEN THEY START TO SIT ON THEIR EGGS ? AND WILL THEY SIT ON CHICKEN EGGS TO

[MountainMarans2012]

I have two Muscovy hens that are 33 weeks old and starting to lay eggs . At what age do Muscovy hens generally start sitting on their fertile eggs to incubate ? And will they sit on chicken eggs as well ?

I had some hatch their first broods at 8 months old about the same age as yours. They may not go broody during the winter it just depends on your climate. Muscovies will set on chicken eggs, but there are some issues with that. Chicken shells are thinner and muscovy hens may crush them. Muscovy eggs take 35 days to hatch instead of the normal 21 for chickens. I wouldn't let her have a mixed clutch. If she does hatch chicken chicks I would take them away as she may lead them to water and drown them.
