@derek420colorado ..when I Hit outdoor winter conditions my girls sometimes go into a kind of suspended animation..they Do reveive when the temps pick up again.
Not as Hard as your freeze..but it might be worth switching on the warm again and see if any respond...
Sometimes they need time to get over the Shock....I'll keep me fingers crossed.
If they do Perk..Don't even try to Feed them for a few days..feeding with low transpiration causes bud-rot..
