Take out all the grass except what is needed to cover the pan,,,,I like green grass best.....take out the duck for now
Sometimes you move the big males toilet and mix it into the "others",,,,,,,,,,this can slow production
Move a trap to the new toiler sight,,,,,(probably a different group of otter)
Clean the dock off of good
you need to figure out were they are entering the dock and face the trap that direction on the toilet area,,,,,,,
