Probobly about 50 eggs total. The only problem with the hovabators is they turn off and on allot. The temps are not stable at all. If you do use one make sure you use large tubs for the egg holders so they hold a stable temp. The tiny delli cups will fluctuate too much. And dont open it unless you have to. It loses all its heat the second you open it and it will take a while to get back up to temp. I have 4 hovabators i used when breeding Leachie giant geckos and they worked great for the money.
