My small flock free ranges, but mainly hang out around the ponds. I would like like to provide some individual nesting shelters for them, but am having a hard time finding some pictures and building plans for just nests. I've seen some muscovy shelters made from barrels cut in half, but they seem too large for my Cayugas. I also thought the shelter needed 2 means of escape if the duck feels threatened. Right now a few ducks are trying to use my goose nest boxes, which are 24X24, I know the ducks need something smaller. Should I just scale down the goose nesting boxes? Any photos appreciated.
