So i got the duck house built and am laying out the fencing. I'm hoping to pretty much build it big enough that they will be safe all the time. I'm sure on weekends I'll let them out so long as I am home to monitor. Question is...what type of land is best? I'm assuming grass, but I dont want to take up all of my lawn for the ducks. Can I expand the area into the brush or will twigs/prickers hurt them? i'd be able to clear away most of the brush but its still not nice soft grass... Thoughts?
