So someone around my neighborhood had to have been feeding peanuts to squirrels because my ducks used to find them every day and LOVE them. they stopped finding them so i bought them some. they are unsalted and get about 2 a day and they go “nuts” for them. they eat the shell and the peanut inside. is this okay for ducks to eat? i looked it up and can’t really find any information on if it’s safe or not? the peanuts are the kind in the picture! thank you!
