Gunny, Rosie, and Gene.
J.T. did all the naming. Gunny is after R. Lee Ermey (J.T.'s a huge Mail Call fan) and Rosie as in Rosie the Riveter. Gene is the canary and we don't know what sex it is. For now, "he's" Gene as in Gene Simmons (yep, J.T.'s a KISS fan too lol) but if he turns out to be a she, we'll switch it to Jean.
