did this happen to anyone else as where the last few days of the second week my temp seemed to jump up so i had to do more then a half of circle turn on the thermostat thingy just to keep it at 99/100 degrees is this because the chicks inside are taking up more mass so they are creating their own heat and dont need so much extra heat put in to them so the heat in bator rose? if you know the answer then please let me know thanks
