Are My 7 week-olds OK at 48 degrees F?

[BigSkyChickens]

I put my 5 girls in the coop on Sunday, and I just need a little reassurance that it's not too cold for them. Coldest temps were: Monday morning: 50 degrees, Monday evening: 56 degrees and this morning it was 48 degrees.
I'm probably being riduculous: it's Calfornia, and the chickens have feathers!
I'm sure this sounds familiar to y'all: the move has been harder on me than on them. The first night I was waking up every couple hours to look out the window. LOL.
The chickens seem very happy in the coop. They are not huddled together. They are jumping, flying and exploring their new space.
Thanks a bunch, BYC people, you have been so helpful, sharing info.

I think they will be fine as long as there are no drafts.

I agree with Jody.

Just keep an eye on them... if you DO see them starting to huddle, then it's probably still too cold. But it's only 45F here this morning, and all my youngsters are out running around...

Thanks, folks! That puts it all into perspective - to hear from somone in AK.

They'll be fine if they're 7 weeks. Our 6 week olds are outside, but they had a heat lamp. Last night it died, and in the morning they were just as happy and healthy as ever.
