Another change! We've fenced in the larger area outside their completely enclosed paddock. This larger area is full of grass and weeds where they can enjoy foraging during the day when we're home and the cat is in the house. The fence has an electric wire near the bottom, and another at the top to keep predators out, also to keep the horses from leaning over to eat grass and ruin the fence.
At first the ducks were afraid to be out there, but today is their second day out so herding them out was much easier. I took their food out there first thing this morning when they were hungry. (Follow the food...) They are taking to the foraging idea quite well and seem to enjoy nibbling on the grass. Everywhere they go, they still go as a pack. Ten ducks all together with one large white one taller than the rest is pretty darn cute.
