I have been separating my hens and drakes at night due to aggressive mating behavior when they were in small enclosed spaces, but during the day when they ducks are in their open range (fenced just the same) area had not had a problem. Today the drakes began aggressively attacking one hen repeatedly (all three at once), so I guess they are now separate entirely. Although none of of them seem too happy about it ( the younger hens are quacking loudly repeatedly like they do when they are upset). The actual question I had was, after the last such aggressive attack, I moved the hens to another pen. I was sitting near the drakes and they came over to me and one of the drakes attacked me. They have nibbled at me before, but the one drake (my favorite of my ducks) literally attacked and was biting very hard. Which he was not allowed to continue! Anyone had this happen before? Really was quite disturbing. Suggestions on how to discourage the behavior???
