This banding is on 3 Blue Head Pionus chicks approximately 25 days old.  To put a leg band on a chick you must point the two front toes and the one long back toe forward and slip the band over the three toes while leaving the shortest back toe in normal position. Then after band has passed over toes and knuckle then slip short back toe as well through band... if it is hard to slip  back toe through to the proper side of band then you must use a toothpick to help pull toe through band. All 4 toes should be on the same side of the band. Be sure letters and numbers on band face the right direction before inserting band on for easy reading when band is placed on chick.
