Unfortunately I don't think we have pics of Arnold but I will look -isn't that always the case. Will take one of Frankie (and Basil and Boris) while I'm there and then Gordon. Frankie was a bit smaller than big softy Arnold, but both Frankie and Gordon are in the same 'rearing' coops, so you will get an idea of size difference from the coop in the background. Arnold was over 5Kg (perhaps 12 lbs), Gordon is under 4Kg (perhaps 8 lbs) which is the same weight as some of the hens. Still the hens will appreciate the weight difference! Not the biggest Wyandotte though. Our friends silver laced cock Victor (killed by a fox) weighed in at 15lbs and stood 3" taller than Arnold and I bet there are bigger.
