I have a couple of call ducks and am going to be getting more. I want to do the raised pens method for the ducks. I was planning to work on it today, but it's raining. Great for the ducks, not so great for me. I have found a few pictures on-line, but not a lot. Would love to see more pictures. Also, I am looking for something to put for them to swim in, but all I am finding do not have plugs. What do you suggest? Do they have plug kits or...? Thanks so much!
