Any blood?
I was once told any blood on pigs, get it covered or else.
My last pigs I had, 4 weaners, nasty little sods they were, don't know what went wrong, but they went for the sheep, they went at me a couple of times, I think in the end, I booked them in sooner and had them done for the freezer.
To be honest, NEVER had pigs since, these 4 put me off, now I buy 2 sides of pork once a year.
One thing I won't have here is nasty animals, I may be a soft touch for a bloody hogget? (Tugger), born 24/12/14, never lambed, lived in house for 7 months with the dogs etc, (gets fat over winter so I have to put her on a diet so she doesnt cark it whilst being sheared!) but nasty/fighting animals, (towards me never mind each other) they're gone.
(On another note, 3 psycho ewes I got in last year, bought 4 in, 1 went this year, think I'm the bees knees now, 1 in particular is incredibly friendly, runs to me most mornings! They have no idea how close they came to departing!)
But, crazy cows, gone, nasty pigs, gone, ewes that refuse to accept that charging me, charging the fence, charging my mum, definitely gone!
