Home made? I will make a guess and say,, you can or you don't have to.
I have a bator with a fan, and when the eggs go into lock down, the fan still runs. I also have a bator with no fan ever. When the eggs go into lock down, no fan.
Yes homemade. Has worked well for me. Hopefully will do with these as well. Really want them to hatch. Pretty chickens and productive. Of course that's what the Internet says and we all know how at goes.
