Thanks for the info. One question I have is what did you do for venting? I read holes on the bottom and top of unit but how many and how big? ThanksI built one last fall out of a Mini fridge that I got off Craigslist. So far we have hatched 7 emus, and at least 20 chicks so I says it works. The trick is low voltage stuff I installed a transformer then used a regular stat to control it with a fan and light. Just let me know if you need help. I do HVAC for a living so getting certain temps is my job. lol
what exactly are the holes for? To help with heat flow, oxygen or ventilation?The number of holes I guess would depend on the size of the bator I guess but I would do at least one in each corner of the bottom , one on each side and a few on top Im not shure exactly though. I used a pencil to gently make a hole in mine when I made it .
