Today the sun shined and we were able to finish our escape proof duck pen. We have sturdy hog panels, with the little holes, sunk in the ground and that is covered with bird netting all the sides and the top. We also have a shaded area for the ducks and a little kids swimming pool. We planted tall grasses and some other vegetation in there for them. Tomorrow we will put the electric fence around the outside of the pen so the ducks can't get to it and predators can't get to the ducks at night. We also need to build a duck shelter of some sort for them. I love it totally functional and I think it is nice looking too. My question is I think I should put something on top of the dirt to make it a little easier to drain and I don't know. I just think I should. Do you think I should put sand down or what and if so how much? Thank you!
