How to determine a good egg layer?

[mustangsaguaro1]

I have a young OEGB pullet (7 months old). She just started laying a few weeks ago. The first week I got 5 eggs from her, 2nd week 6 eggs and the last week I got 7 eggs. Because she is still young and just started laying, the amount of eggs I've gotten from her so far, based on this info will she be a good egg layer? Here is a pic of her.

Thanks

This chart will help. it gives the average eggs layed per week of the breed.
