don,t use collars,i,m a bit old fashioned lol,but i know what your saying about character,i got the impression yesterday ones going to be very determined and the others a bit less,but it was only first time so time will tell,cheers
Don't have to necessarily be locator collars, could just be a regular collar, pick them up for a couple of quid. Apart from just getting used to them, the only way to mark them apart is to either do something to the ferrets, which i wouldnt recommend (some idiot on here dyed his pink!) or attach something to the ferrets, and a collar is the logical option.
