I have never heard of a snake being happy at a weight and staying there if they are good eaters. If they are not good feeders and stay small would you not want to move this female out of your breeding program and replace her with a good feeder that gets bigger year after year? I would think that you would not want to produce more animals that are " Happy to stay small ". Maybe I am wrong but I try and keep only good strong feeders for my breeder females so my offspring could have a chance to carry on the same strong feeding response. If a female weighs 800 Grams while breeding what would she weigh after she lays the eggs ??
