I will be buying some more ducklings this spring; keeping them for a while in the house for warmth, then moving them out to the enclosed duck yard where 3 Khaki hens rule. The yard is 20'x20', with a 6'x8' house. I was thinking that I need to put up a temporary fence to separate the younguns from the hens until they get used to each other, but I'm not sure how long that will be, or what to do about nighttime. We have hawks, foxes, owls, and who knows what else in the area, so I don't feel comfortable about leaving the babes in something like the igloo style dog house we have (no door). We don't have a lot of money, so I can't really build anything fancy. Most of our extra money for the next few months will be going to enlarging my garden instead. Ideas?
