"Me", I understand that you are a 'proper farmer' too, so you will also not include labour costs nor other fixed costs in working out the profitability of any project. 

If you had to pay someone to look after your mollies, or pay rent for a shed for them, well then yes maybe it would be a different equation.

You've still got room for a fair few costs if you're getting £70+ for them, mind. 

Yes I can work out the costs, and I will.  But not until after lambing.  Remind me in June.

Ok will do, just cost it for you, roughly, if you don't rent don't put in rent!

I rent some land so that does go in to my sheepy calculations, economics bite very quickly when your sheep need to pay landlords and leave something for you. I have some land and buildings etc but they do cost to maintain and depreciate over time and mathematical brains far greater than mine could take account of this to the penny no doubt.

I haven't costed my pets as I think it would probably scare Me and I plan to rear them regardless, we synchronise as far as possible so cross foster a lot and end up with very few thankfully so unlikely to bankrupt us but still. A grand total of four this time two courtesy of the first ewe to lamb with triplets and no udder... kebab anyone?

Described as a 'proper farmer' hmmmm... that hasn't happened before.. one to add to the list..
