New Asil cockerel attacking hens

[nuthatched]

This bird lived alone, outdoors, like most game birds. He was from a really good breeder who wins huge shows. I didn't think he would carry any disease.

He can definitely carry disease.

They’re all about the same age. Pullets are 7 months, cockerel is 6 months. These heritage pullets aren’t standing up to this Asil. Ever lol

I just received a 7 month old Brahma Cockerel from a breeder 2 days ago. He's going through a quarantine period regardless. The breeder said disease free, but regardless you must take precautions if they are, because there's a slight chance they might be hiding something.

Quarantine is important, but I think more to the point is that in the thread title and in the original post, we’re looking at a failed integration of a 6-month-old cockerel into a flock of 5- month-old pullets: it’s not working.

Again, OP, can you tell us about the EXACT nature of “New Asil cockerel attacking hens”? What exactly are you seeing? (Forced mounting, neck grabbing, pecking to the point of drawing blood, pinning pullet down to the ground by her neck, etc.)

We are going nowhere until this question is answered, because we don’t know what is happening.
