Hi all I've just been leg ringing my new turkeys & my bantams but I'm just wondering the 16mm leg rings I've put on the turkey hens do fit (Way too small for the stag so will order more for him & my geese) but they are touching the scales on the legs but can slide up & down, should I take them off & just use for some large cockerels or ducks & buy some 20.6mm ones for the females as well? x
