I worked at a chicken hatchery hatching out baby chicks and one thing I noticed is the boxes at the top always hatched out the best because they were warmer at the top then the bottom of the stack so you'll have to keep that in mind that the top and the bottom are going to be different temps. But you'll have your heat down low and work upward so that should be a good thing.
You'll have to figure out where will be the best place for your probe placement. You will have to use your infrared heat gun. We used them at the hatchery a lot. That is where I first became aware of the red dot guns. Thought they were so cool. Even some of the farmers used them to see what temps the chicks were that came.
I think the oil heater sounds a lot safer than say an electric box type heater. Is it the electric oil filled ( radiator looking ) type or a regular oil heater? Fire safety would be the foremost thing to keep in mind. Also will you be still using heat flex tape with them or just keeping it at 85 And are there any fumes with this heater. I would think the best heater would be the electric oil filled heater which might be what you are talking about getting.
Is there a light in the closet you can turn off and on for day and night simulation?
Hope my questions don't seem stupid![]()
