So many early quitters in one breeding pen

[Dinosaur Village Keeper]

Thanks for your reply! I don’t think it’s the incubator that’s the issue as all the other eggs from my other breeding pen do just fine. It’s only eggs from my WTB roo breeding pen that are quitting like crazy.
My incubator is a forced air so I doubt there would be any hotspots, and I usually keep the vent on top open

Maybe you can borrow someone’s rooster if you want babies quicker? Or even make some cute mixes by putting one of your other Roos in with them.
