Hey Marie,
Very cool. Yep, I wondered why 3:00 was the magic number. So, 3:00 is not magic; it's the changes you made.
Your info is really valuable to us that want to free range any of our livestock. Knowing there are predators out there, I think we should be responsible enough to make a sincere attempt to deter an attack. That's what you did. I love how you made the changes gradually - and fortunately, it worked.
I'm not necessarily all out for just killing the critter, when we've given it an open opportunity to kill. But if we've made an effort to deter it, and it's not working, then I won't hesitate to shoot.
However, we have friends up here that raise sheep and goats, and once in a while, a mountain lion will come in during the night and slaughter the herd; they don't eat the kills - they're teaching their young the art of the attack. You can't deter that - and that's a different story.
Nice going!
Teryn
