Will my chicks freeze?

It's a low of 37 degrees tonight. Will my chicks freeze if theyre outside ? They're 4 and 5 weeks old

Do they have a momma? If not I would move them in. Also, is their brooder or coop area small and short? If so they can cuddle up and be ok, but I would move them in if they didn't have a hen watching out for them.
