Is it possible that the virus in Port Lympne came via Luka?
OF his seven children there are only 2 left. His daughters Vishesh and May Thagu.
Also his 2 sisters died at a young age (8 and 6).
So maybe it came from Belgrade and was spread over Port Lympne through Luka.
It's alsow not easy what to do with Euan once he gets a bit older. Using him as a breeding bull is out of the question, just like Emmet. It is almost a fact that he carries te virus and they are still breeding with him. I would search a new bull for Whipsnade.
But back to Euan, transporting him to a zoo with only bulls like Ieper or Sevilla is also a big risk. If the other bulls there get the virus and die, or worse, they get the virus and go to another zoo for breeding and they infect the whole breeding herd. That way the whole European breeding program could be in danger.
I think it would be best that he stays in Whipsnade, maybe with Emmet. And that they search a third bull for breeding to stay with the cows.
Ore maybe a zoo that houses the infected bulls which can't be used in the breeding program .
