Breeding program: Assign numbered rings to breeding pairs to track pedigrees, egg production, and hatch dates without handwritten tags or tape. 2. Health monitoring: Tag birds that require observation or treatment so caregivers can quickly identify and separate them during checks. 3. Loft or coop management: Use different colored rings (random mix supplied) and etched numbers to manage large flocks, assign feeding groups, or track race and show birds. Notes on ordering and handling Colors are supplied as a random mix and mixandmatch set; there is no need to select a specific color or random number when ordering. Check ring fit before final placement: use the diameter guide above and ensure rings close securely but do not pinch the leg. Regularly inspect rings for fit and wear as part of routine bird care. These aluminum leg rings provide a clear, reliable, and long‑lasting way to manage and identify pigeons and poultry for breeding, health, and flock organization.
