I'm something of a novice at this but I haven't seen this before.
They are usually really placid and friendly: to me and each other.
Today they are acting like something has spooked them (I'm sure nothing has).
Eyes wide, running about, can't settle.
Some are standing with their heads down, almost noses on the ground, head shake every now and then, skin twitching, foot stamping like there is something there (which there isn't). It's like there is an invisible swarm of flies bothering them but there is nothing there.
They are also irritable with each other: headbutting others out of the way.
If penned a few and had a look for fly maggots and in their mouths but I can't see anything.
Some have rued and some waiting for the shearer. It's affecting both.
Any ideas?
Thanks in advance.
