what is the normal average weight for a 5year old greek?

There's a ratio that someone (Sue Donohue???) made up for the mediterranean tortoises. Maybe one of our members can give you the details. I can't seem to find it.

Search "Jackson Ratio"; it is a weight/length ratio, not a weight/age graph. At 5 y.o. it should be about 10-12 cm, but very often CB's can be even larger.

Here is a link to a Jackson's Ratio calculator that I use, which gives you more of an idea whether the length/weight ratio is healthy): http://www.tortoise-protection-group.org.uk/site/171.asp - if you need to convert inches to cm, just use Google for that (type e.g.: "5.5 inches in cm" and it should calculate for you - that's 14cm).

Our captive-bred 7-year-old Antakyan greek is 5.5 inches long and weighs 475g... he's on the small side for his species and age.

One of the little torts I rescued was 5.5 inches long and weighed 275g when I got him (Jackson's ratio of 0.10, which is severely underweight). My healthy 5.5 inch Russian tort weighs 500g (Jackson's ratio of 0.185 = healthy). Plugging those numbers into the Jackson's ratio calculator gives you an idea whether your tort is spot on, overweight, or underweight. There is an explanation of it under the calculator.
