The second ram would require a better look. He's getting that blocky, broomed look but maybe flyingbrass is right.
LBH hit the nail on the head. "Big" is a relative term. Sheep vary so much from unit, area, sub-species and State, that it would be hard for us to know unless we had more info and a much better look at that ram.
Except for that one ram, all the others need more time on the mountain.... like 3-7 years.
