I have 3 red foot tortoises & 2 believed to be growing at a normal rate, the 2 1/2 year old is at 2.3 kilograms while another of 1 year is close is over 660 grams but the third is stunted at only slightly over 520 grams also at one year of age & his coloration is darker I believe of another South American country origin. Is color & size variations an indication of sex or meaning from else
