Advice Please!!! My ducklings are 6 weeks old now & growing so fast!!! I haven't sexed them but my husband thinks that the 1st born is a male because my drake is constantly attacking that duckling & he's ( the drake) getting more aggressive with the attack. Over the weekend all the ducks were out swimming & luckily I was out doing yard work, when I heard all this commotion & the drake had the duckling on the ground attacking & trying to mount it, the duckling was squirming around & gasping for air. I got him off the duckling & separated them but it happened again the next day. I realize that my drake is showing dominance but when will it stop??? I hate to continue to keep them separated but I don't want an injured or dead duckling. I figured since the ducklings are getting bigger that my drake will leave them alone but the problem is just getting worse.
