6.5 weeks upper 20’s temp heating mat/pad use question

[Magnolia76]

Thank you for all of the sound advice! I wanted to update so other newbies can see to stop worrying lol. It’s 31 degrees. They had no heat, no heated pad either. They roosted in a row and their bodies were warm. They are up having breakfast and doing just fine! They’ve now been outside of my bathroom for a week and at 6.5 weeks are fluffed up and thriving. Makes me happy! Thank you all!
