i got a new costal hatchie yesterday that nippy as hell and what i do is leave them in there click clack for 48 hours so they settle then take them out with a hook and let them crawl up my arm and get my scent,i take afew nips but when there hatchies the bite doesnt hurt so its all good,i handle them for 10 minutes a day and increase the time by an extra 10 every week,after that they usally settle done and are pretty placid
