had a questions for the more experienced breeders...

...I got my first clutch tonight, which came from a 4000G female.

9 eggs, candled them, 4 good, 5 bad. (the 5 bad where obvious, smaller, yellow, sorta wrinkled, etc.)

Is there a rhyme or reason for this? is it something I did or did not do?

I assume its the luck of the draw.

Thanks for your time.
