HI, I have 3, 1 year old Pekin ducks, 2 female and 1 drake. I also have 6 baby ducks 2 pekin (1 female, 1 Drake), 2 female mallards, and 2 that I can't figure out what they are, but that isn't the issue. The issue is my 1 year old Drake is singling out my smallest Mallard female. My Babies are nearly 3 months old and the last 2 months they have been in the duck pen with the older ducks but separated by a baby gate. Is there anything I can do to keep the older Drake from picking on my young ones.
