My Gecko is an oddball?

[GeckoGrace]

I have had my gecko for 2 years now, and she has been weird when it comes to laying. I got her from a classmate along with what i soon realized was a male leo, and my girl laid an egg a week after i got her. Her first egg was a dud and only a single egg, which might be normal. But over these 2 years, she has been weird. She had all fertile eggs after her first, but up until her last clutch last year she only lay one per clutch. Her last clutch last year was 2 fertile eggs, but they didn't make it. I am still baffled at why she is like this. Does anyone have any ideas?

I've had a lot of different laying profiles with geckos including:
--laid for 2 seasons and then stopped ovulating
--laid 20 fertile eggs one season, fewer than 10 next season and then stopped laying
--produced healthy offspring one or more seasons and then all offspring had defects (with a proven male who had no defective offspring with different females)
--only laid eggs outside the lay box and the eggs were never fertile
--laid fertile eggs every season for over 6 years

Each female seems to have her own laying profile and you can see what your female is like.
