How I feed my Ducks without issues ..;)....
Yours are older so go buy a poultry finisher feed and mix it with scratch grains that contain less corn...No more spinach and things should balance out..Also Ducks do good on dry Cat food...as a treat once or twice a week..:)... protein..;)...

Hello....A wildlife officer will not respond because what is happening is natural in the Duck world...You have a mated pair and then bachelor Drakes all trying to mate the Hen..Ducks do not mate for life , only a season..The Drake she chose as her mate has to constantly keep the bachelor Drakes...
