as in, when they fall they hurt themselves? Because I've never had this problem.

Do you mean nips? Never had a problem with this either as I fed babies every couple hours, but many breeders do that over crowd tubs and only feed 1-2 times a day. If i see more than 1-2 nips on beardies from a breeder, i would be wary. Whole feet and tails? Very wary.
