There is no "usual" time frame - unless you use an ultrasound system and can track and breed based on follicular development.
In a nut shell: the female grows her follicles year round, then according to seasonal cues she will commit a certain amount to fertilization, if she has not been bred, she will reabsorb them, if she has been bred she will use the stored sperm for fertilization (ovulation).
With this in mind if you breed the female when her follicles are larger and she is further along in her follicular development she will ovulate sooner than if she still has small follicles. So there is no real set time for this part of the breeding process as there is for the time between ovulation and laying, etc. It's very dependent on other factors.
Hope this helps. ----- Tosha
