We live in a suburban neighborhood, and have a lovely coop with five layers. We have them quite secure, but on the off-chance that one or more should ever make it out of our yard, I'd like them to be returned to us! I've been looking for legbands that we can order with markings of our choice, so I can have our phone number on them. All I find are the type that large-scale production would use: different colors or code numbers. Any idea how I can keep my girls safely tagged for return to us?
