I also agree with 5-6 every few days, or 2-3 per day.
IMO overfeeding has more to do with egg production than temperature based on my experience so you are asking the right question.
Doing this, I have prevented a lot of my females that I keep as pets (no breeding) from laying eggs for over 16 months. I think Sandrachameleon has prevented hers from laying for up to 18 months if I'm not mistaken?
If you overfeed them & keep them too hot, they'll lay as early as 6 or 7 months.
Also it is well established that if they do not have any visual contact with a male, it will also help prevent egg production.
(PS I agree with the above statement that she looks receptive)
