Our ducks have to go in a hen house over night, as they don't have access to a pond and we have lots of foxes in the area. As they lay in the house ( 9 o'clock here lol) , sometimes in the nesting box, one broody duck actually produced some ducklings in there late last summer. It was not an ideal situation and I am hoping to have a new "birthing and nursery area" ready later in the spring. I hope to tempt them with either a marked cooked egg or a replica egg to sit and lay where I want them to. I did not encourage them last year to nest in the garden (they tried! The Blue Swedish being the most stubborn and I hunted her eggs down every day in a different place, never found them all), as they have to go inside. My plan is, should one get broody, I'll move the whole nest and try to lock the duck in with it, too...You probably know that most ducks are lousy mothers, they just didn't seem to care about their offspring. It was quite traumatic to loose 4 out of 5 ducklings to bad weather and the sparrowhawk in a matter of days, but I will try again, better prepared this time! I wish I had known about this forum last year, it would have saved us some trouble!
