Hm, very interesting news. They're most likely looking to send out Emily and her daughter Gigi, since Emily is a half sister to their current breeding bull, Johnson, and one of Fort Worths bulls, Colonel, is a half brother to Natasha at ALS (Natasha has four female calves and two grandcalves all living with her at ALS).
Overall, I support the move, for ALS, Emily and Gigi are the most sensible two to move since it's a clean split, no breaking matrilines, it still leaves ALS with two distinct family clans (Lily line and Natasha line), and ALS has 16 animals right now, 11 of which are breeding or potential breeding cows, so it's no real loss for them in terms of breeding numbers. For Ft Worth, they currently have two fairly valuable bulls, a new, fairly large exhibit complex, and only one matriline composed of four animals (Mom Rasha, her daughters Bluebonnet and Bluebelle, and Bluebonnets son Bowie, who is now separated from the family group). It would give Ft. Worth one hell of a potential breeding herd, and also allow them to breed within their own group without needing to transfer in or out any new breeding bulls for the next 20+ years. They most likely would transfer out one of their current cows, Angel, as she is not related to the Rasha clan, is a non breeder, and does not get along with Rasha terribly well, so her and Rasha are kept separated, but I suppose she could potentially be integrated with the ALS girls too. Who knows on that one. Personally I would just send her out, but that's just me.
The only tiny concern I have in the back of my head, is Ft Worth suddenly having 5 (though realistically 4 since Rasha is pretty old) potential breeding cows, and squandering the potential of the group by taking a classic US approach of only having calves every 6-10 years per cow. Assuming they keep things proper and actually breed their animals regularly though, I support the move fully!
