My females will usually eat till 2-4 weeks before ovulation.
With my males it depends, most eat less but still eat throughout the breeding season and some go off feed and just want to breed.
I totally prefer they eat all year around except during ovulation

I started breeding in November and have some follicles in a couple snakes and have several close to ovulation finally.
Snakes seem to have their own time schedule as to when they want to ovulate, just keep pairing and keep track of sheds and feeds.
