Lows in the 30's & 40's, can I put 11 week old chicks outside?

The weather has been weird this year, and we are experiencing fluctuating temperatures. I bought some started pullets and they are 11 weeks old. The hatchery said that they need to be in 60+ temps until they are 12 weeks old. Normally that wouldn't be a problem this time of year, but the weather is weird. I'm desperate to get them outside- but the low will be 39 tonight. Will they be okay? They are fully feathered.

They've been able to outside in cool weather for months, they'll be fine. The hatchery is wrong.

My broody who hatched in february stopped keeping her babies warm at night at 6 weeks. They're fine to go out now.

I have my 1 month old chicks out just this weekend when it was warm and this week it'll be getting to the 40s at night but 60s/70s during the day. Their chick coop is a small box with about 4 inches of wood shavings, they cuddle together, and I close the door at night.T hey have the majority of their feathers already and yours are much older so they should be good to go.
