Over weight bearded dragon?

[Midge]

Ok so I own 2 14 week old bearded dragons. One I believe is to be a boy who is small and looks like a healthy weight for his size, the other maybe a girl but acts and looks like a boy so I can't say for sure yet. The lil one runs around like no tomorrow while the bigger one would rather just lay and do nothing. Now I know it's common of them to be lazy but the big one looks a bit fat I suppose. I haven't weighed them yet this month so I will later but is there a rough guide to go by?

Thanks all
