Cockerals

I have 4 cockerals and 11 hens and i want to seperate the cockerals to give the hens some rest. But the thing is it that i have made the pen and hut and everything but the problem is : i have 2 cockerals in with the hens at the moment( a dutch bantam and a bantam aracana) .And i have another 2 which are a chicks they are 11 weeks old and they are a R.I.R and a chamois polish. I want them all in the same pen but will they fight and really hurt one another?

They can see the hens though .. ummm what do i do now becuase i can't build another pen 

Its really hard to say, some cockerels are quite happy together, whilst others will fight to the death. Occassionally you just get a cockerel takes a particular dislike to ONE, but is alright with the others. " key points....make sure they have plenty of space to stay away from each other, with hidey corners etc, and OBSERVATION, when they are together, watch them. General squabbles and squaring off to each other can be expected, but you must be there to step in if it turns more serious.  I would guess that at 11 weeks old, the oldies shouldnt see them as a threat, so its worth a try.
