I can get a good count on the turtles I have as they come out to feed with the rest of the critters. Kind of funny to watch them feed and then a nice CC come smack one. I usually take them out as I can not stand to catch them, plus I figure more will come back later in the season to clean up any dead fish. I figure what ones my CC do not eat the turtles can have.
A few years ago the ducks were enjoying the food as well, this was November during deer season and they scared me to death when they took off. I had no idea they were there. Pretty neat site though.
I do not like to share with the Coons though, they already broke a few spinner plates.
