I had bought an incubator a at a coop and it didnt come with a fan. Do i have to have a fan to hatch the eggs or can i do without a fan in the incubator to hatch veiled chameleon eggs, and what is the best process for what to set the eggs in while they are in the incubator and how far to set the eggs apart and everything else. I just want to get yalls opinion on everything.

Thanks Ronnie
