I am thinking of buying colored bands for my hens so I can tell who is 1 yr old and who is 2 or 3yrs old. what do others do? I had one chicken that someone used a zip tie to band her and it grew into her leg causing her to always hop (hense my name Hoppy). I don't want this to happen to any birds I band. I do let mine free range in the warm months so it needs to be a safe method and most of my hens are indental.
