I have 3 10 week old ducks that have been raised with chicks I got at the same time. They get along great with my chickens and sleep with my silkies on the floor at night. My problem is, they constantly drown the floor of the chicken coop by playing in the waterers. So I have decided to section off the part of the run with their little pond in it and build them their own house. But I have a couple questions. Two of the ducks are females. Do I build nesting boxes for them inside their new house, in the pen somewhere or will they just choose to lay eggs on the ground of the pen instead? Should I lock them up at night or just leave them access to the pond and run all night, which I think is pretty secure? One of the females has taken on the role of property security alarm though and I worry she will 'go off' at random times during the night if left to see the yard. If I do lock them up, should I keep water and food in their house for nighttime or leave that stuff outside for day consumption only? My concern is that I will be using hay/straw for their bedding inside and I know someone said they need water if they eat or they will choke. I don't want them to be nibbling on hay or bugs during the night and need water. Any help would be greatly appreciated...thanks!
