I think I understand what you are asking.
Males will mount females and other males as a demonstration of dominance. It is not always done for reproduction and fertilization. This is part of your overcrowding problem. Don't worry about this too much. When the females want to be bred, they will let the males in.
I think our climates are similar and over here, my females start laying eggs in late December or early January. They keep laying about every six weeks until it starts to get hot in May or June. This varies with different climates though. There is no "breeding season" the males mount them all year long. You will get more breeding, more eggs and more fertility if you keep them all warmer at night in winter.
I found another neat trick (Thanks to Neal) to increase hatch rates. Leave your eggs in the ground where they are laid and covered up until late May or early June. Then dig them up and put them in the incubators. Cover the areas where the females lay with a wire cage of some sort. No shade or cover, just wire on a sturdy frame to keep other females from digging up that area to lay their own eggs.
