M.Kitchengirl, being a chef you'd think that drake would be in the oven... lol. This is the first bad behavior my runners have ever showed towards any chicken let alone chicks. Right now it's as if they are on speed or something. They are just buzzing around the yard and in the woods where it rained enough to make small pools. Works for me but they must be eating something that is making them go crazy...... lol. I wonder if there is duck crack in the woods that I don't know about. Usually they stay to themselves.
I was starting to think he would have to end up on my rotisserie too, and I was dreading it. I have to run the yard on my own - my sweetheart wants very little to do with my hobby, and that is fine - and I had no interest in killing a named pet in the side yard on a sunny afternoon. Been there, done that. I am glad I know HOW it is done, but I will wait until there are no local farmers raising beautiful ducks & keep baking up a storm with all my duck eggs.
I started out only wanting girl ducks. In the chaos of picking up my first 3 ducklings I ended up with 2 boys. It is hard for me to give up on an animal once I take on the responsibility of raising them, and I wound up trying to make it work. My drake charmed me into giving him a shot.
I had a sense he was after my chickens in a less than G rated way one day & sat there watching him. Then, he tried it, mounting my EE hen in the backyard.
I started to range them separately, and he became increasingly angry when he couldn't get to the chickens.
One day I came home & he had found a way through the fence & was chasing my Wyandotte. He grabbed her by the chest & started to drag her into the bushes. I got to him, and scared him off & went to lure the chickens back into the coop so I could contain the drake & fix the fence. As I escorted the girls down the hill he came FLYING down the hill - he'd never so much as gotten an inch off the ground before - and landed on top of my Wyandotte & started brutalizing her, right on top of my foot. I grabbed him & tossed him in his duck house where he proceeded to thrash about & throw himself at the hardware cloth trying to get out the entire time I wrote his Craigslist ad.
He is a good boy now, with 12 more ducks than he had before & is not causing problems at all - probably too worn out - at his new home. My girls started laying the next day, and haven't stopped. Honestly, I think he was stressing them out, too.
Good luck with your boys. Everyone told me to add more girls & I was waiting for my order of ducklings, but he was gonna kill a chicken & sometimes you have to do what is best for all, not just one.
