Bonded roosters?

I got 2 Bielefelders that hatched together and they seem to be bonded? They mostly just hangout with each other and don’t seem to care about keeping an eye on the girls while free ranging. They aren’t human aggressive which is fantastic but i noticed they’re the reason one of the hens is an outcast.

I saw her hiding from the boys and she made a break for it to a different area of the yard, and they briefly chased her.

Obviously, they’re not doing their job. I’m wondering if getting rid of one will shift the others priorities? My main purpose of having a roo is for protection but theyre too busy being bros to care about the girls. 🙄
