I recently (Feb.2021February 2021) began feeding a flock of 35 Ravensravens in my backyard. In the Springspring and Summersummer months I have 3 to 4 families of Mallardsmallards and Woodieswoodies raising their families in my pond and swamp. Am iI setting myself up for a problem Byby continuing to attract Ravensravens to my yard.? Will they terrorize my ducks and steal their eggs.? I guess iI prefer seeing the ducks but enjoy the Ravensravens also. Looking for advice.
