How to make great incubator?

[LukSadReptiles]

Hi everyone, I have small fridge and I want to rebuild it to incubator, but it's small and when I put tubs with eggs inside I think it will be not so easy to make good temperature circulation?(sorry I'm not native speaker so sometimes i don't know correct word) - I mean same temperature everywhere inside incubator.
I add pictures of fridge.
Can you help me with this project?

It should work fine, if your worried about even temps throughout the incubator, you just need to add a small computer cooling fan. You need to put heat tape on the inside regulated with a good quality thermostat like herpstat. Put the probe somewhere in the middle. That's how I have mine setup and it's much larger than yours and since I added the fan, temps are even everywhere. Before I added the fan the top was 2-3 degrees warmer than the bottom. as long as you put in a fan and get some air movements, your temps should stay even and the thermostat will keep the temp where ever you want it, I keep mine at 89.
