I read all the post tonight not sure I trust the heating element I used one in a brooder with the same setup it melted the end off the heater can't wait till you get the GQF up and running I would like to know about the heat source . I hope to start my homemade soon and am locked in on space . also will have to build trays and turners. It's to big for LG turners . there will be a incubator top and hatcher bottom .Is the brooder a square bower or the old model .post pictures when you get the chance
