They do come off before, but there are places to go. Last night they just kept coming back to each other after separating. Like I said I forced a time out last night. I had hoped they would stop arguing while I was there to stop it if it got bad. I don't know why anyone would want to watch cocks fight it is not cool.
They have been near each other for three days through the cage. Once it opens there is lots of space. Until then there are several ways to hide even in the coop. Unfortunately, I am not sure if either would be inclined to hide. If all goes well though, they will be ok in the spring when they each have a group and free range. I don't plan on any new cockerels except in my HRIR group if I raise a good one in the spring, but they are in a separate coop.
No it isn't cool to see at all.
One year I put all the roosters in a pen/coop together for winter and it went pretty well. I put a little heat on them to keep the coop above 10F.
The next year I decided to do it again but it didn't go well. I did it at night like the previous year but I didn't have good roosts in that building. So when I turned the light on they all went at each other. I needed about 10 hands. I grabbed one rooster and held him while I tried to get a divider between the others.
I ended up putting most of them back in their respective buildings. You just never know how it will go.
