So really getting back to the first question Atherton or Palmerston there is really no way in telling apart from tacking where he came from , or waiting another year or 2 to see if he keeps on growing, thanks for all your help, think i will downsize his feeds just to get a little of that fat off, but he does lose it over the winter.
He's a big fella alright, but as Browns said, he probably was a looker in his day...
get him to do a few laps around the backyard every other day for a workout...
