Hi all! So I'm getting two Cayuga ducklings within the next several weeks and I plan on making their housing out of wooden pallets. I need to know a few things... 1) what is the most important things to have in a ducks coop? 2) can they day range or should they have a run? (I have chickens who day range and they seem safe and happy) 3) I have a shallow creek in my backyard...will they get a notion to swim down the creek and not come back? My yard is fenced but the creek part is not. That's all I can think of at the moment, any first hand experience and advice is greatly appreciated!!!
