Hi mate must admit that my jills havent bit me yet and I have had em since kitts.
Bold statement bound to get nipped now!
I have been handling thier kitts since they were born and no probs there either.
I have found that all kitts bite tho, its just their nature.
I normally let em have a nip but once the realize your not food and your not gonna hurt em they generally stop!
Handling little and often is the way to go, be bold but not nasty, dont snatch away cos that just tempts em to nip.
Perseverance and patience, good luck
