Seramas do they really need special treatment?

[SpotTheCat]

I am looking at maybe getting some Seramas, do they really need a heat lamp/be indoors in winter? At the coldest which isn’t often it gets to 0c. I don’t know what size they will be

I dont have any, but looked into getting some. What I read is that they don't do well below 40 degrees without supplementing heat for them. But maybe someone had a different experience.

No mine stay out in the winter with the big chickens. They are more fragile though and can get sick easier.
