Wing clipping involves trimming the primary feathers of adult birds wings to prevent them from flying. Sharp shears can be used to trim off ONLY the first ten flight feathers of ONE wing. This causes the bird to lack adequate balance to be able to fly. A very experienced person should only carry out this procedure and inexperienced students should never do it unassisted as incorrect wing clipping can result in pain and severe injury to the bird. Wing clipping will allow birds to be kept in a pen or run without a roof, as they will not be able to fly out.
Leg bands can be used for identification of ducks and geese. The school farm may use different coloured leg bands to identify birds born each year. Leg bands must be checked regularly and loosened appropriately or removed if they begin to become too tight. Legs bands that become too tight can cause pain and severe injury to birds.
