Keeping cockerals

Hello,
I suspect that I have five cockerals out of my broody's clutch of 7. I don't plan to keep any for breeding so i think they might be for the pot but is it possible to keep a 'flock' of cockerals. I could put them in the orchard away from the hens. I have heard that they don't try to kill each other if they can't get to the hens.
Is this true? Has anyone managed to rear more than one cockerel kept seperate from hens?
If this is not true what are my options?
They are only 5/6 weeks so early days but mindful of the future.
Thanks
Michelle

Hi, i will also be trying this, but from what i've read i think it will be best to have an older one first and add youngsters after

Morning!
I think my plan is to seperate them once cockerel behaviour shows and put them in the orchard. They will have a large area to roam and a safe house. If they stand by the only bit of fence they will be able to see the garden with the hens but hopefully that will not cause them to start fighting each other.
What I don't know is
1. When are they ready for the pot?
2. Will i need to keep them in their new house for the first three nights like i did with my POL hens?
3. Foxes - i am assuming they are just as vunerable. So far we haven't had any problems  but the hens are in a walled garden (just a bit of fence by orchard). I am a bit concerned that putting the cockerals in the orchard will alert foxes to the hens.
4. There is an old pig sty in the orchard that we can convert for the cockerals. I guess they just need something to roost on??
As this seems to be a bit unusual i shall report back on what happens.
