I have 2 drakes, a mallard and a khaki Campbell. They are normally the best of friends. During the day they free range. At night, i have an enclosure (a run and coop) they are put in. This is the only time I feed them their crumbles. The problem? My mallard will not let my khaki eat ( i have 2 separate food and water bowls). My mallard wont even eat- instead he forces Darwin into the coop and 'stands guard' and wont let Darwin out! I've tried putting Darwin to bed before Delaney (mallard), but they will walk along the enclosure quacking and pacing until they are reunited. I feel bad for Darwin! Ive tried putting food and water in the actual coop for Darwin, but Delaney will then hop in the coop and peck Darwin until he gets out. Bottom line, Delaney does NOT want Darwin to eat. Period. Suggestions? Or should I just let them be?
