Cockell only flock fighting

[Blue is my chicken]

I wouldn't get one just for that purpose. If it were me I'd just keep them out of line of sight from the hens and they will calm down. Hatchery Brahmas might be a bit more aggressive than pure Brahmas but they won't kill each other generally. Sounds like you have plenty of space for them, except you don't list the size of the house, only the run. If you have perches/roosts in there (many brahma breeders don't) make sure they are all the same level, otherwise they will scrap over the highest perch.

Okay I didn't think it would be the best idea to get a male for this purpose
We hatched these brahmas from eggs we got I don't know how good quality they are
I forgot to check the size of the house that is all
We are still building their house so at the moment it does not have perches (it has a roof a floor and 4 walks just no perches)

Very often, male only flocks do not work. They may fight to the death.
Rehome or sell/giveaway them for someone supper.

That is to bad hopefully we can find another solution
