Thanks for the update!
How likely is the introduction of a new unrelated bull? It is about time .... since Thorn's passing, don't you all think!?
When Thea was born it was stated in Animal Park that the stud book had put them on breeding hold. After many years of success I guess the gene pool was quite extensive and with Thorn reaching later years it'd been unfair to ship him out so I guess they were just waiting until he passed(obviously we're at that stage).
I wouldn't expect a new bull in before the end of the year at least. I wouldn't expect Ella or Gertrude to produce any more calves given their ages, Kate may be retired as well as she's now 14yrs so 16/17yrs as a new mum again if a bull arrived this year.
