Khaki Campbell sleeps in roost with chickens

[annasophiabee]

My female duck is sleeping in the roost with my chickens...is this normal? I have a male duck that nests in a little straw pile but the female duck somehow flies up to the roost (about 4 ft high) and sleeps with the chickens. Any tips and advice is appreciated

My muscovy roost. I haven't seen a mallard based duck roost personally.
