Hi,
And on your original question....
There is no set timeframe from locks to eggs I'm afraid - it all depends on the female.
This video is really good at showing how to feel for follicles - that can give you an idea of how things are progressing.
And this web page is great for knowing what the steps are.

Best of luck.
