Hi Roada, I also have standard breeds,and Seramas. My Seramas get alone great with the bigger birds, just be careful when you first introduce them of course. I never let them together unless i was right there with them so i could stop anything that might happen, i did that for a few weeks, and now my little Serama roo runs the coop.
I had seramas in the past.. They are not cold hardy. I kept them in winter quarters during cold inside heated garage. I also do not have roosters big or small. I Only keep hens , and the seramas were able to get along with the standards. I had 3 Easter Eggers and the rest were bantams.
WISHING YOU BEST
