A friend of mine had a pair of mallards who decided to nest in her very large high window box.
She was very worried about how the young ducklings would get down to the ground safely. She tried putting up a large sheet so they could slide down. Whatever way they did it they got down safely.
The main room in your house...


and they are back too. The 'bovver boys' from last years hatching are still around and throwing stuff around including my plant labels. They are comical to watch but seem to be permanent residents now and we wish they weren't, what can you do though. Would prefer ducks really
