That is the strangest swale ewe iv'e ever seen and my guess would be that next doors ram is the father .   Either ram would sell at market, the white one is still a lamb so if fat say £1.50 per kg ,  the black one  £20 -£40 as a cull

But at the moment they stink, presume this would create the meat taint I've heard about?

Oh, yes.

Oh, yes.

Looks like they'll both have to stay a while then 
Does smell ease off in Spring,  like billy goats ?

[waterbuffalofarmer]

I dont see why not. Rams only smell around tupping time, so anything from spring to summer should be ok, it may be an idea to seperate him in a couple of months, making sure he doesnt stink, and then slaughter him. I would keep him seperate for maybe a couple  of weeks before slaughter in case of smell. The smell is at its strongest now, when he is pumping full of testosterone

Don't keep him in his own, it's not kind to herd animals.  But you could keep him with a couple of wethers for company.
