Weight isn't a big of a factor as you might think..age, weight, build, fat stores, over all health of the animal.. while most people look at 1300 grams as breed-able and 2007 is well with in that range. There are a few factors that go into this, is the animal a lean thin 1300 grams or is she a stocky 1300 grams. I bred a 1100 gram 2006 female just fine, small clutch but still..is the animal recovering or just recovered from an injury or illness? Is she eating good ect ect..
