Organic Pest Control???I moved the sheep into a new "cell" today and after I was done, I noticed these wrens riding around on the sheeps backs. I assume they're there for an easy feed.
I have a fly trap near the sheep that is baited with something that smells like bad meat. It's meant to protect them from the type of flies that cause "flystrike", but maybe flies just hang because sheep smell a bit (just like sheep, not bad, just different to people).
