I have a small colection, 20 ball pythons, and I hatched out 15 babies this year. Everybody ate ASFs. Period. All hatchlings ate AFSs. Then the military moved me to CA with no real notice whats so ever and AFSs are illegal here.
ALL of my snakes are eating rats and mice no problem.
I do have a picky Blk Pastel but she is picky on when she eats not what she eats.
I completely believe this is a bad myth. As soon as I move again I will restart breeding ASFs. Large litters, small adult size, little smell - all are great incentives to stay with ASFs in my book. All of my hatchlings sold no problem as well. The buyers did not believe in the ASF myth either...
