Help in Harry Potter : Half-Blood Prince

someone help i'm stuck in Harry Potter : Half-Blood Prince. In quest search Eggs and rose oil for Ron. How do i get it?Thanx before.

Erm... the rose oil: go to the owlery and talk to the red head there, she wants something in exchange for it. I think it's some fanged frisbees (not completely sure though)
and the eggs: I have no idea, I can't remember. Have you tried asking people?
