Advice | Aggressive Rooster | Trying to introduce new hens

[Butt_Nugget_Hut092]

Hey,
So I have a small flock of silkies which contains...

• Onyx - Black Silkie | Rooster - Est. Hatch Day: May 1st, 2024
• Topaz - Chocolate Silkie Hen - Est. Hatch Date: May 2024
• Opal - White Silkie Hen - Est. Hatch Date: May 2024 _ Laying - started 10/21/24

And I'm trying to introduce these two hens into his flock...

• Amber - Millie Satin Silkie - Est. Hatch Date: March 2024
• Ruby - Millie Satin Silkie - Est. Hatch Date: March 2024

I'm not attempting to introduce them cold turkey either. They have been in an introduction cage to keep them safe but to allow them to get to know each other for almost two weeks...
He literally sits there and stalks the cage. Back and forth. Pacing infront of it. If I take one of the new girls out and attempt to set her down... he immediately charges with the intent to harm and kill. He's never been like this. I raised him from a chick and he was so loving and cuddly.
Now all of the sudden he's not accepting the new girls and is instead trying to kill them.
And anytime one of my bantam or serama hens comes near his run... (My silkies are in a different coop and run then my game bantams and seramas) He charges at the run fencing and attempts to get to them to hurt them.
He's also started biting at me every now and then.

I'm confused as to how my sweet boy turned into a brat. And what to do about introducing the hens? What's up with his behavior?

The roo in question... he's so cute... turning out to be a peckerhead though.

Sounds like he is strongly in puberty and hormones are high. I would remove him from the flock and introduce the hens. Let him and the hens mature (several months) and then try to reintroduce him.

Adolescent cockerel, immature and full of hormones.

Pullets about two months older.

He probably sees them more as threats to his position as dominant flock chicken than as two girls to welcome into his flock. They are probably not much with putting up with his snotty bratty ways. They expect more out of their roosters. He is not a rooster, just a cockerel.

I don't know how easy it will be to integrate just the girls together but I think it is worth the try.

You can try letting them all mature some before you try again. I'd at least want the girls laying before I tried that.

Some cockerels never work out. They never mature into responsible well-behaved roosters. I don't know how he will develop but it may be that you will eventually need to get rid of him or keep him permanently separated.
