I'm a first time duck owner, and I need some help! The Campbells are almost 7 weeks old now, and for about the last week the biggest one ('Bad Duck') has been pecking the others on their back or wingtips. Should we be worried about this? Why does Bad Duck do it? Is this normal teenage duck behaviour? Also, we got 12 birds straight-run. The plan was to keep 4 or 5 ducks, assuming we have that many, and kill the drakes and any extra ducks. Is it going to cause problems to have so many drakes until they're big enough to be butchered? We were thinking of doing 4 when their juvenile feathers have finished coming in, and another 4 or so when the grown-up feathers are in. Does this seem sensible? We're read up on the duck thing, but not done it before, so any advice would be lovely! Thanks, everyone!
