I recently(Feb.2021) began feeding a flock of 35 Ravens in my backyard. In the Spring and Summer months I have 3 to 4 families of Mallards and Woodies raising their families in my pond and swamp. Am i setting myself up for a problem By continuing to attract Ravens to my yard. Will they terrorize my ducks and steal their eggs. I guess i prefer seeing the ducks but enjoy the Ravens also. Looking for advice.
