I have a juvenile Corn, 2 juvenile Milk and a baby King snake. should i be brumating them in this winter/during the cold months?

They are in the same room as my BP’s that are out of QT. they are in tubs, no hot spot but ambient temp is 80-82. the temps outside are in the mid-to-high 30's during the day and get to freezing at night but as i mentioned it is a warm and comfy inside. So should I remove my Colubrids and put them in a cooler part of the home?

My Corn continues to eat. She can now take adult mice. my Albino Milk is also up to adult mice but refused the last 2 weeks. she was in shed tho but the most voracious feeder beforehand. my Anery Milk takes several hoppers and refused last week. my baby King has become very aggressive, striking and rattling her tail. she continues to eat 2-3 pinkie per feeding tho. all prey are frozen/thawed.

So should I be brumating them? what temps and how much light do they need? my least active one is the Anery Milk who likes to hide but each one is still scoots around a lot. Are the food refusals of my Milks due to their need to brumate? Will brumating chill my aggressive baby King out?

Ok, lemme know whatcha think. thanks!
