Can anyone give me pointers about what kind of housing to build for ducks? They were sleeping in an outdoor pen and we lost most to a bad coyote attack a few weeks ago. They are now sleeping in a pretty well fortified aviary, and running around the yard during the day. I need to build them a shelter of their own, but can't find anything specific on nesting and housing needs of ducks. We now have 2 different breeds-- a female mallard and another that may be a runner, but I'm not sure. It is black with black bill and feet and stands upright like daffy duck, but maybe not quite so upright as a runner. I'm not sure if it's a duck or a drake. oh, and a chicken (cockerel) who thinks he is a duck. The birds were all hatched by a middle school girls' class and given to me. The chicken had some mates, but they were killed in the attack, and now instead of hanging with the chickens--who have their own coop--he hangs with the ducks. Also, does anyone have advice or experience about digging a pond? We have a very small pond, but I try to keep the ducks out of it because it's too small for them and it has some nice water lilies that get tangled up in their feet. For now they've got a wading pool, which they still seem to enjoy, but we know it isn't a permanent solution. They look pretty much full grown, but haven't fledged yet. Any advice appreciated. Thanks!
