Hi mate you will struggle to buy a working ferret a good one anyway they are rare,its very rare that people with a good working ferret will ever sell it,there are many ferrets advitised as good workers but they have probably got some fault like skulking just inside the hole instead of coming to hand or they are biters.Imo stick with the ferret you have got and given time he will come good,don't be in a rush to get him working he will take to it in his own time, never force the ferret,you could buy some young ferrets this year and get them going in september,a ferret that you have bought up han
