Nova - My seramas are let out with my big birds, and do fine, although they tend to stick to their own and stay in close to the coops. They do have a separate coop/run that they go back to each evening. I would think with milder breeds like polish and SF, they'd do just fine. Not sure if you have other, more aggressive breeds. Most folks who live in areas with cold winters do provide heat for seramas, so that may become an issue for you come winter time...
