I would not recommend removing the cuttlebone and mineral block. Many birds simply like to chew on them which is good for their beaks.
Lemony probably isn't actually eating too much of it, so unless you are giving her additional calcium supplements she should be fine.
You're going to want to keep a close eye on her though.
Does she happen to be in condition right now?
I'd be careful during out-of-cage time to ensure there is no mating taking place.
