If you don't tie your kangaroo down, sport, she's gonna be missing next time you look . . . .
Seriously, one kick from a nervous mare can end a stallion's million-dollar career, so yeah, the breeding shed looks pretty kinky. Most operations put the mare in rear hobbles and pad her hind legs, in addition to the usual tail bandage, etc. I did hear of one old-timer who preferred letting nature take its course, would put the mare in the next paddock to the stallion for courting, then just turn 'em out together. Risky, but I'm sure the participants enjoyed it more.
