My new thermostat that I've had for 2 weeks went haywire and heated the Livingroom from 69 to 82 before I woke up from the heat (my room was at 91) and turned the heater off.

In about 4 hrs the Livingroom went back down to 71 since it's the cooler room in the apartment.
My society finches seemed ok.
But the parakeets r shaky.
I turned on the heat 1 degree and it seemed to help some but they still shake a bit. Not sure if they feel cold or just stressed.
I know the roller coaster up and down not good for birds.
Society finches seem to be handling it ok.
Is there something I can do to help parakeets?
I have liquid vitamins but they don't drink much.
I could put it in their bath water but not sure if they should bathe today and it would stain them if they did try to bathe with the vitamin drops in the bath water.
The weather outside is 61
