I thought they gave him back to you because he was still being a...well...you know.
I wish you could share your story with another member on the boards who refuses to protect her mallard hens from her gang raping drakes. They only need to catch one ONE time and it would likely inflict mortal wounds. If you don't mind, I'm going to look for the thread and post it here for anyone else who may be able to help.

No, my sister still has Howard. He is being both a blessing and a pain over there. He does keep the mean hen and rooster in check, but he is also attempting to catch and breed my sister's pair of 19 week old female Chinese geese. If I still had that drake he would have been dinner long ago, I will not tolerate a drake, gander, or rooster abusing the ladies. Luckily, my rooster is a punk to me, but protective of his ladies, and my young gander doesn't dare threaten me (I kinda pinned and sat on him the one and only time he looked at me sideways) and is also protective of his ladies. My Cayuga drake is the question, at 5 weeks old it is way too early to tell if he is going to be a gentleman or dinner.
Why on earth would anyone allow a bunch of drakes to gang rape the hens? Not only can the hens be killed, but egg production goes way down and ducklings can be killed as well! Anyway you look at it an abusive drake is bad.
