Large and bantam cockerels

[stroudy36]

Hi guys
I have a couple of roosters in separate coops but really want to change the layout so it is one large enclosure the male bantam rooster is a year old and friendly to the larger rooster who is only 9 weeks old will they remain friends or is it worth a separation I figured if I have bantam and standard hens then they have there own ladies to look after... is it worth putting two houses in

My head rooster is an Old English Game Bantam and next in line is a bantam Plymouth Rock rooster. I also have a few other bantam cockerels, and then I have a full grown Marans cockerel, full grown Appenzeller Spithauben cockerel, and a young Barnevelder Cockerel. Everyone gets along just fine 99% of the time. I've never seen the bigs fight with the bantams but occasionally there are tiffs within their own weight classes. I house all my birds together with two coops that share a large run. They get to free range for at least a few hours every day, except during the middle of winter when days are too short during the week.
