Murrey Gr bull is plenty deep. Would like to see more length in neck, back & rump. May have too much shoulder as other said, but I'm not sure about that. Would like deeper flank. Small, which is typical of the breed. All in all, decent bull.
Charolais has tons of lenth of neck & body, but a little short in the rump. Also would like to see him deeper in the flank. In "working clothes" but appears to have ample muscle (which the breed is known for.) Good clean front end.
Don't know what the 3rd bull is. Appears to have a long neck, reaching for feed. NEVER take a "head on" shot of cattle - looks awful. Big head - no body. I realize you were playing with him, but I know I would never post such an awful shot for the world to see of Macho. Eeeks - talk about a picture worth a thousand words. Anyway, nice that they all have good dispo.
