I've just charged a friend £100 for a 16month Heb hogget, 18kgs cold, butchered and vacuum packed. I would normally charge £120 for that if it was not to a friend. I don't charge per kg as it gets quite complicated, taking into consideration your slaughter and butchering costs, plus the fact that people will just want to buy the best cuts and leave you with all the ribs and tough stuff (I get all that made into sausages and burgers with my own spice mix).
If you overcharge then you lose a customer for next year, if you undercharge then you lose out. It is difficult
