I did have the ducks & chickens all fenced in together till my Golden Cascade Drake kept raping one of the chicken hens. Only the same white & black chicken all the time. So the chickens(3 hens) started going over the fence/free ranging in the neighbors walnut orchard. Then I noticed the 3 hens went up in a walnut tree, on a kinda low branch & would sleep there. Only the Rooster would be roosting in the little coop. I would still find 1 or 2 eggs in the nests where the chickens would roost. I fenced the chickens a different section with plenty of room to free range but, still next to the ducks. I have a good sized corner(in the fenced area) all covered with new tarps and lots of clean hay, a wire cage with hay inside it & on top of it. I put a shelf with hay over the top of the cage and a lil bakers rack with 3 shelves & hay for them to nest and roost in. There is always food & clean water. The tarps rap all around & hang down 3/4 of the way in front but all supported/not flapping in the weather. No rain gets in or under, and there are about 10 or so eggs in the very back in a nest. I did this all by my self, took a while in the rainy super cold weather(with Many swear words). My niece crawled inside and told her mom that it was super cool in there, looked like a fort. After all this stress & hard work to satisfy these birds, the stupid chickens at dusk still fly back up the tree to sleep since 1 goes the other 2 follow, only rooster stays. Snow,sleet and rain chickens sleep in tree, back to eat at day light. The GC Drake, he continues to stalk the chickens and sleeps next to the fence/chickens in the rain & snow. The 2 chicken hens go in by the ducks, just not the white & black hen. ~sorry, I Wasn't trying to make this look like a chicken post. Julie
