I just got 2 new red foots today and my new scale and 100g calibration weight for the scale to make sure it weighs right. The bigger one is 6 1/2in and weighs 736 grams the 2ed one is 6in and is light at 584 grams, she feels very light to me even before I weighed them. What are normal healthy weights for red foots at 6 1/2in and 6in? I just don't want nothing to happen to them. Thanks Scott
