Application advice of an expert..."....I keep will have two rings on, one ring carries the ID number the other is for sexing, pink for the hen and blue for the cock. This way I can look in to the main aviary and pick out cocks and hens at a glance This is how the rings arrive in sets of 10 with an applicator. Numbered for ID and coloured for sexing
Take a ring and slide it up the applicator until it splits with the number facing the right way up. Then put the leg through the split as shown. Finally, hold on to the ring and pull the applicator away Job finished to remove a ring just push the applicator up the leg and the ring will open
