Has anyone had good success with outside portable nesting boxes? I just built a new coop just for my ducks so they won't make such a mess of my chicken coop. It's taken a bit of work to get them used to going in there at night instead of the chicken coop, but they are starting to get the hang of it. Some of my ducks started laying last month and at first most of them went up to use the nesting boxes in the chicken coop. Two of them now have started to sit on their eggs, but the others have stopped laying in the chicken coop and are laying somewhere outside. Originally I was going to build some nesting boxes and attach them to the outside of the duck coop, there would be entrance holes on the inside and the outside would have a hinged roof for egg collecting. I haven't built those yet and now I was thinking maybe it would be better to build little external nesting boxes. Any ideas?
