Some breeds of chickens are more flighty than others. To hinder them flying it is possible to trim their wing. ONLY TRIM ONE WING PER BIRD!
First have someone hold the chicken for you with the wing out stretched. Look for the primary feathers – they are the longer ones at the front.
Trim the primary feathers about 5 to 7 cm on one wing only. Remember that wings are like fingernails, if you over trim the wing, it will bleed.
Never trim the cover feathers. You can also trim the secondary feathers (the ones behind the primary feathers)
By cutting only the primary feathers, when the wing is closed, your chickens still look pretty. Her efforts at flying will be once sided though!
Clipping causes a bird to lack the balance needed for flight but lasts only until new feathers grow during the next molt, which may be a few months in young birds or up to a year for older ones.
