Feather coat or lack thereof

[BladeFireLight]

Last moth my girls molted. Then last week we had a heat wave in the 90s. The all started pulling their under coat to cool down. The coop and run looks like a pillow fight.
In three days the nighttime temp is going to be 35.
Should I be worried?

That's unusual behavior, they shouldn't have done that. They might still be molting. Don't worry about the coolness.

Nope, it will bother you a lot more than it will bother them.
