Agree with all the comments, great sign! Best of luck, the breeding process is fun all the way to the end, especially first time. You'll be elated when the eggs arrive and then hatch. Cool stuff. If you make this a habit annually, some friendly advice ... I track the weight of all my breeder girls every couple weeks. In addition to the telltale signs, the weight is a good measure of progress. Breeding a dozen girls this year and most have gained 400-700+ gms since August. So keep feeding her aggressively while she's building, its amazing how the appetites explode and then just as suddenly stop. Again good luck and keep us posted. Cheers.
