Need advise !?!?!?

[The Farm]

Agreed on that the pen does look great just got to watch out for those hawks! Lol

I don't know the do like cleaner water but the pen looks fine .

I wouldn't think the mergansers could tolerate that water?

Yea that should be fine for them does it have a top?

Okay thanks for the advice. As I need a lot of it. No it doesn't have a top. I am going to put a pump, and water fall in it soon. Any ideas how to do the water fall?
An the sod will be on soon hopefully.
