I'm guessing I might have messed up.

I just got my Pedigree 9 with the star stats that I want tonight. So I've begun leveling her up and feeding it. I figured I'd start with one stat and then move on to the next. The bird is level 21 at the moment and I have used all the previous levels on Stamina.

This is where I'm guessing that I messed up. Her stamina is at 450/500 and I still need to level the other stats, but I only have 30 more levels left. With the Rank 3 food giving 15 stats per food I'm not going to have enough feeding sessions to level everything.

I had just remembered that stats raises as they level, so should I just rotate on the stats I want to level or how exactly should I be doing this to max out the stats that I want to max out?
