So i have two ducks (8 weeks and male and female) and right now they live with the chickens. So i want to separate them. I want to do that because the chickens are bullies and i want my pair to hatch ducklings this spring. So, How much will it cost for a basic pen for the two and also for ducklings(run with pool and egg place)? I was thinking about buying a already built one but I want to see if i can get it cheaper.
