Try lizards instead of mice the racers and coachwhips seem to be terrified of mice till their 3 feet or so and their also not ready for all that fat, lizards are a very lean meat, I had a two clutches of 18 eastern coachwhip eggs hatch and all the eastern babies that I fed a pinkey to tossed and all the babies that I forced lizards gerw fast and never tossed up food.
