General purpose numbered leg bands for poultry. Used to identify individual birds within a flock (for example, a bird with an injury that is being monitored for healing) or to identify laying hens in a flock of different ages. Numbered bands can be used to further identify birds in a flock already banded in the same colour - for example 500 hens already tagged with un-numbered orange bands but you need to identify 100 of them for treatment, injury healing and more. Available as a package of 100 orange bands numbered 1 through 100.
