There is no certainty when eggs may be laid it can be may like it can be february like it can be november. There is no timeline because folicular development itself can take anywhere between 4 to 8 months to start with.
There is only 1 timeline and it is from ovulation to egg laying even that while the average is 45 days, I have seen it anywhere between 40 days to 69.
Now as far as breeding receipe their how many, you can ask 10 different breeders and get 10 different answers from cooling or not, pairing starting time, to how they introduce and how often, what YOU need to do is find what works for YOUR animals and yourself, the more you observe the better you understand and learn when to pair without wasting your male.
For example proven females I don't even start pairing them before they move the the front of their tubs (nothing to do with the month just has to do with the fact that I know their follicular development is well on it's way and that now is the time for pairing)
In my experience your animals will teach you a lot if you know how to read them.
