Hello, This is my first post! In about a month I will be acquiring 6 Welsh Harlequin ducklings. I had chickens years ago but this will be my first experience with ducks. I'm building a 20'lx8'wx8't predator proof enclosure with 2x4's & hardware mesh. They'll have the opportunity to come out and roam the yard when I'm home in the evenings and days off, but I wanted to make sure the run was big enough for them to be comfortable during the day. I'll post pictures when we get started next Sunday. We're also setting up a water reservoir to use dirty duck water to drip irrigate into raised garden beds. The thing is, I want to be able to use dirty bedding for a compost bin, which after extensive reading I arrived on Straw Pellets. But I'm still not sure what bedding would be best. If I use pellets, I'll have to make sure that the run/coop has a full roof on it, right? Or is a roof necessary no matter what? I originally planned on having half of it with a roof on it because it's so large, but then got to thinking about the fact that I'm in Georgia, so it's super hot, and we get random torrential downpours. So I'm guessing full roof is best? Maybe even a 1ft splash guard on the bottom? For those of you that use old bedding in a compost bin (I'm in the city so I can't go stash a pile at the edge of the woods, I have to use a container) which bedding works best and breaks down quickly? I was reading that Straw Pellets are better pH wise for compost than Pine Pellets, and that regular or chopped Straw and Pine Shavings take a long time to break down. Also I was reading about how pellets can be beneficial for odor control. I have to be on top of the odor so I don't upset my neighbors.
