I would wait as you have different types so they will start laying at different times. Is she your only white egg layer? It sounds like she is starting to lay and a white star is a good layer. Has her eggs been double yolks as that is very tiring for a hen.
If they free range have you checked the garden for eggs...mine will lay under a hedge, lavender bush and even checked out the sage plant

Yes she is the only white egg layer, some of her eggs have been doubles, she did lay today (at last) with a shell on too, so things are looking up for her, I hope this continues and the trouble with her is over, I would obviously like to keep her)  I will keep you updated, thanks everyone for the advice

one more good egg and no shell again

Well she can lay eggs with shells, so I think she may just having teething troubles getting the routine right.  Like I said at the start, if all they ever lay is soft shells, that seems to be how it is forever onward, but there is hope with this one 

If she is still laying a mix at the end of her probation period, you'll have to make a judgement call on whether she lays enough good eggs to earn her keep.

I think as long as she is laying 3 good ones a week she is safe!! I think thats a fair deal
