incubation temperature

[Tania]

Hi guys, I know its maybe already asked, but I don't seem to be able to find it.

I was wondering on wich temperature you incubate your ball eggs.
I also will have corn eggs this year and I was wondering if I can set my temp on 29 degrees celcius, so it will be a bit too hot for corns and a bit too cold for balls. Is this possible or is it better to get another incubator or are there other possibilities that I don't see right now?

Thanks already!!
