Congrats first of all! That female is really amazing. But yeah, if she is seeking the heat at this point and preparing to shed out. My inclination would be that the ovulation may be over. Especially if you don't see it within the next couple of days. I think the heat seeking occurs post ovy and thru the pre lay shed. Incubator time is what I feel. Best of luck and can't wait for these. Lol.
