Hi John,

Ducks seem to produce duck poo in greater
amounts than what they seem to take in.
So hopefully you have a nice, big strong filter.

They will eat plants and some will eat
fish.

Watch your water quality and how your plants
and fish are faring.

I've had ducks visit my pond and they sure are
cute. The labradors though find it insulting to have
ducks on their pond and chase them off.

kathy :-)
