Are hatchlings easier to convert to f/t if they have a feisty appetite? I ask this because I never had experience with switching HATCHLINGS to f/t. I have experience with switching adults and juveniles to f/t and some were difficult and impossible and some were easy. I am interested in a hatchling bp and the reputable owner says he never took f/t, but has an aggressive appetite and in my experience with adult bps that the aggressive appetites switch easily.
