My evidence is that challenging Elephants don’t change. A prime example is Mya,she was disruptive at London and the same when transferred to Whipsnade. In fact Mya caused a ruckus between the herd,this led to the herd being split. Once Mya went to Spain in 2019 the herd was simultaneously reunited as one. Since then there’s been no further problems.
Ive never known Mya as a problem elephant, I thought it was the fact that she never really got along well with Kaylee.
Whipsnade always kept the London girls seperate from the rest of the elephants, but following the deaths of Gita and then Azizah, Mya was left without the support of the elephants she was closest too and fought for dominance with Kaylee. This led to her having to be separated and sent elsewhere, rather than Whipsnade having to hold two seperate herds.
