New 1.5 Year Old Rooster introduced to 10 hens.. Help

[aart]

They have an entire coop that's even bigger than this run

That could hlep.
Why I asked.....

What does coop space look like?

Photo's are so misleading, I thought that the building in the back of the run was the coop.

If you have space, just let them out, and by morning they will be in love.
