I keep on reading "buff Orpington ducks" on this site. I had buff Orpington chickens before and they were amazing. They used to lay almost everyday and used to successfully hatch the eggs they incubate. That chicken I got from a friend and I think they brought it from another country, so I don't think I could find like it. It was later eaten by an animal that looks like a crocodile or something like that. Are buff Orpington ducks similar to the chicken version?
As for the idea, I like that idea of having a type that incubates and a type that lays a lot.
If I get pekin ducks, I think I will make the niacin more concentrated in their water then.
As for exercise, everyday morning I let them out for like half an hour to walk around the garden while watching them, then later around noon when there is sun I also get them out to let them get sunlight and also to get warmer if they want to, with a place that has shade so they can go there if it's too hot, and I let them out for like another half an hour and sometimes less. I have to keep watching them because my cats always try to hunt them and I have to keep removing them away when they slowly come close. The ducks keep running and following each others around the garden, and they also eat grass, sometimes only puts thr grass in their bills and act like eating but not actually eat it. As for swimming, I will try warm water later.
