thanks for your help guys - I haven't had a close look yet. Mainly because there have always been people around and I might get a few dirty looks if they see me looking too closely at this area lol Makes sense what everyone has been saying because I know how to tell the difference between castrated sheep, goats & cows etc and those that are entire. I was pretty sure stallions would be the same.
When I bestride him, I soar, I am a hawk: he trots the air; the earth sings when he touches it; the basest horn of his hoof is more musical than the pipe of Hermes. ~William Shakespeare
