I read on a post here a bit back about using colored small elastic pony tail hair ties as leg bands. I bought a package and was excited to apply them to our flock (6 1/2 weeks old) to help identify each girl as an individual. We have 3 EE, 3 SLW, 3 PBR and 3 BO. I chose green, blue and purple. The band went on easily and fit great allowing a lot of room for growth but when I put her down to apply another band to another chick everyone ran to her and started pecking at her band. I removed the band for now until I hear from you experts. Will they lose interest or will they peck and cause injury?
