Blooie - yes, I actually just raised it today after cleaning them out and putting shavings in for the first time

It's so amazing how fast they grow!
I also lowered the temp to number four yesterday,really worried me as I thought they might need it higher at just 4 days old but on number 5 they seemed to spend more time on top so lowered to 4 and they all slept soundly and seemed perfectly fine this morning!
They are currently in an unheated spare bedroom with the window open (only because I'm an anxious new mum lol,more for my benefit than theirs) with the intention of moving them out in the brooder to the coop with the big girls this weekend.
So my question is.. when they go outside to the coop, do I keep the heat pad temperature setting on the same number or raise it to compensate for the pretty chilly weather we seem to be having atm (barring yesterday which was 79f) currently low 50s dropping to low 40s or just keep it on the same setting and see how they act i guess?
We do have a pet cam on them atm so we can see them at all times but not sure our wifi will reliably reach to the coop, so I will only see them when I go out there...which is multiple times a day anyway normally.
Sorry for the probably silly question but i'm a born worrier lol.
