Why my white sheep can't grow up?

[elwingwhite]

I bought two white sheep many days ago, first one I remember I feed 5 or 6 times (4hr once), it grow up.
Then I bought second white sheep, I feed this sheep one day more than two times over one week, but it still can't grow up.

Is anything wrong with my sheep?
Please help me, thank you!

They should mature after 5 collections. Do not store it or you'll start over. The grown sheep can be stored but don't store the babies unless you want to start over.
