Hi I have 14 18-week old Khaki Campbell hens and 2 drakes. I had 30 until 2 weeks ago but most of the boys were processed as the ducks are primarily for eggs for us. Now one drake is being aggressive to the other drake, not wanting him near the girls or food and even biting him while he's mating a hen. I thought 7:1 was a pretty good ratio. Is it due to their age? Is there any other option other than sending the aggressive one to Freezer Camp? Thanks.
