Ok females tend to go off food around janurary for us. We start pairing in november and by january rolls around is when females start to go off food and some have noticeable follicle growth. You can kinda tell who is gonna lay by their eating habits and if you see them seeking the cool side of the enclosure and bowl wrapping. Alao keep in mind some females will eat all the way through ovulation and egg laying and never go off food. There are also females that wont even have a pre lay shed after ovulation they just dump their eggs around 45 days after ovulation and heck some ovulate so fast that you never notice it even if you stared at her 24 hours straight.
