Mines do not respond to their names, or rather, it seems everyone responds to everyone else's name but the one I call.
I think it's rather the intonation and sound direction they respond to, rather than the actual name said.
Most of them being born here (but the 4 olders), they've all kept their original names, however, I rarely deal with them individually since a colony of 12 is a bit overwhelming during out of cage time (it's rather "BEWARE GLIDERS EVERYWHERE"), which can also explain that they don't really know who is who.
There is one word they understand above all, oddly, is "mealy"... then I'm sure everyone rushes to me, no matter where they were hiding.
