Too young for no heat?

Picked up 2 chicks this morning. They are between 5 and 6 weeks old.
My plan is to have them as seen in the photo for a week or 2.
Thoughts? Should I bring them in at night.
Southern Ontario weather is just starting to go below freezing.

They were on heat in a garage. But I do feel most people leave the heat on for too long.

They're ready for no heat, of course if you see them huddled up with obvious signs of coldness you may need to wean them off the heat by giving them some everyday. but theyre fine for sure

I left them outside for an hour and 1 was ok another was not. My thought is maybe a little younger. I brought them inside. Have them next to the wood stove and the little one has perked up. Think I’ll have to wean a little. No heat inside for a few days than outside during the day and inside at night for a few then all should be good.
