Crazy attacking drake

[Jessi1210]

I have a 4 month old Muscovy drake- felix.
Lately he has been charging after us (the humans who live here) and biting.
He had a brother- however poor Henry injured himself and passed away about a week ago

He's in a large enclosure with 6 chickens and 6 other ducks- they are younger than him, males and females.
He attempts to make the chickens and usually only attacks when we try to break that up.
However now he has started charging me when I go in to feed or water them he used to be so docile!

I know some of it could be sexual aggression i assume. And I know I need to have at least 3-4 females per drake. Which is why I purchased the other 6, I hope that they were girls. It's looking like at least two are, maybe four.
(It's hard to find sexed ducklings here)
They are too young for him to be mating 2 of them are about 3 months and the others are a little over 2 months.

Is there anything I can do to curb his aggression? It's becoming a real problem.

Funny my Drake is named Felix and he is a blue pied Muscovy!
The picture is from the day I got him. He was poorly treated..
But he is gorgeous now! Just need to take a pic of him again!

Try catching him and locking him in a dog kennel for a couple of days. I did this and My felix never did it again

I edited it above but I don't think it uploaded fast enough-

So he basically needs a time out? Haha

Pretty much! I bought Felix from a young Teenage girl who didn't properly take care of her animals. ( I bought him and 4 other females) He was okay the first 2 months then he started to attack me or my guard dog. I had enough and stuck him in a cage for 3 days and he hasn't done it ever since! I've had him for almost 6 months now.

If he were mine, I would separate him from the rest of the flock until the ducks mature. If he succeeds in catching and breeding the chicken hens he may cause them to prolapse resulting in their death.
