I have swimming pools for my ducks out in the yard. Then I have one in the doe goat pen (where my 2 drakes live) and one in my "far" pen where my mastiffs run most of the time - but once in a while my does go over there to graze. I have Muscovey and even though I clean the pools daily - the algae is horrible. can I put feeder fish in there to help with it. Is there pros or cons for the scovey with doing this?
