I wouldn't worry about the dearth of eggs but the lump concerns me.

That is definitely a potential problem.
What state are you in?
The space between the pelvic bones doesn't change overnight. It is a gradual response to hormonal signals.
Have you checked the space between the pointy pelvic bones? If the space has narrowed, that is a sure sign that molting is imminent and the autumn/early winter egg break is on.
Often the comb will lighten and shrivel somewhat...
As @Eggcessive said, there may be nothing wrong. It is almost 2 1/2 months after summer solstice and a 1 .5 year old bird should be getting ready to molt. That will almost always stop ovulation.
