stabaliizing a still incubator temp

[Freitas farm]

Looking for some advice : ) so my lil giant incubators temp fluctuates. The room has pretty stable temp besides mornings the temp in the room does drop a lil, theres no drafts either. In the morning it drops down to around 99.3 and then afternoon it goes up to 100.6 give or take. is this normal? any advice is appreciated. Thanks : )

That's actually very good for a LG. One tip that may help; put a box or something between any window and the incubator to shade it from sunlight.
Have a good day.
