You are correct in thinking she may not lay this coming season - but that is not always a bad thing.
You would be able to do a full quarantine without getting tempted to break it for breeding and she would get a year to grow.
You would also get a year of getting to know her quirks and habits - which can only help when it does come to breeding.
In the end she would be larger, in good body condition, and likely to lay a larger clutch all other things being equal.
