It takes 48 hours of incubation, it hatches at 24 hours I think. After that it needs to mature for two "Login Reward" cycles (obtain the login reward twice) before you can use it in battle. It will lose health the entire time at 10%/day, that's just how it's set up.

You only need to give it a stabilizer once every four days though, so don't even bother until it hits 60%.
