What temperature is too cold for chins?

[Kara315]

I know they can take the cold a bit better then heat, But I was wondering when does it get to be too cold for them? I always have the air on for them and close the door, so when I walk in, I can really feel the cold, of course I'm not wearing a winter coat, but it got me wondering at what temp does it start getting too cold for them?

When their water becomes ice its to cold for them as far as adults, newborn babies should be 60-70.
