I ordered 20 runners for March delivery. I got 1 male for every 4 females. I never had this type of duck. I have a brooder ready for them, but I am going to build them housing over the winter. I am open to advise on what they prefer for their house. I am sure they will need to be locked in over night so they don't become snack crackers. Will they go in on their own like the chickens? Or will I have to round them up each night or use electric poultry netting? I have an auto door for my chicken flock, it is the best thing ever!!! I want to make sure the ducks are safe at night. I will be building nesting areas, should they be placed low? Like a small drum withe the side cut out or a nesting box? How about their water, are they big swimmers like he other breeds? I had muscovies in the past, I am just not familiar with runners. (My muscovies liked the creek out back behind the horse pasture better than living here! The fence did NO good at all!) My idea is to keep them(the runners) out on the horse pasture and have their house with a fence yard around it so they can be turned out. Also, does this breed fly?(like my other run aways) I read some about them, but your experiences are the best teachers. I am very excited to hear about yours and receive my new additions!
