This past spring I bought three pekin ducklings not knowing what gender they were. Well my luck they all three ended up being drakes. This is my first time raising ducks so I'm still learning as I go along. They are around 20-23 weeks old now and from what I can't tell mostly full grown. They all are definitely makes with big drake feathers. I haven't had any issues with them till recently I noticed them fighting a lot more. One of them is the leader. He picks on the other two. One of them was born with a slipped tendon and I didn't catch in time to fix it. He's a happy duck just hops along on one leg...and loves to swim. Just today I had the one with the lame leg in there pool and the leader one got in after him doing what I assumed trying to mate. The gimpy one is noticeably smaller and I was scared the bigger one was going to drowned him. I guess my question is will they always fight and try to mate with eachother or will they grow out of this? Also do you think I should keep an eye out for when the lame one is in the pool and keep the leader one off of him or should I just leave them alone? I read a couple threads saying their drakes got along just fine....I just wanted to make sure mine were being normal lol. Thanks!
