Sounds great, FW.

Another way is to weigh yourself, then pick up the sheep, step back on the scales and subtract the difference.

That's why I asked if it was for assessing readiness to slaughter or to dose - if you can do this, it's nothing like 40kg yet!    Another thing I've done in the past is pick up the collie dog, put it down and pick up the sheep - I know my collies weigh about 16-18kg, so I can judge if the lamb is more or less than that this way.  (Doesn't work with young collie dogs, they wriggle too much!  )

Both great ideas

Surely it also depends on breed a commercial breed will be generally they are cheaper than a rare breed. (Not much but enough I should think)

I'd like to add I dont keep sheep but I'm putting it out there
