My Incubator Is Mucking up

[Axle Quails]

my incubator temp keeps going up and down :S

It was 37.5c earlier and now it keeps going to 34c - 32 c

And it home made and hand turned

89.6*F is a little too low, try to keep it warmer somehow, can you cover anywhere that its leaking heat?

Is it still air or fan forced?

Fan forced And it got air vents
