We have four little female runners who are nearing laying age (just turned sixteen wks). I know they are known for their "un-broodiness" so was wondering if they even make use of nest boxes. Will they sleep in them or just use them for egg laying? My sweet husband built them a beautiful house and run and will build them nest boxes as well but I don't want to have him go to the work of doing it if they won't be used by the girls. Also, do we need a separate box for each of the girls? Do we put the boxes in now or wait for the first egg. I have noticed that their pelvic bones are much less rigid but can still only fit two fingers between them. I'm guessing that we are still a few weeks from the first egg? By the way, we have found our runner girls to be quite calm but very busy. We did do a lot of cuddling with them from the start and they spent the first four or five weeks of their lives in the kitchen (where the family spends most of their time). We would have been fine with four nervous Nellies but are so pleased to have ended up with our four cuddlers. One of them expects to be picked up first thing in the morning so that she can climb up and lay her head on our shoulders and nuzzle under our necks. So, so sweet. We are first time duck owners so have nothing to compare to but we think we have the best ducks in the world!
