The zip tie is a good Idea. I like it better than the velcro idea. THese will stay on a lot better. A guy here in town who wns a chicken farm knows where to get poultry leg band s at really good deals. He gave me the web adress here a few months ago, but like everything else I lost it. I am going to see if I can get it from him again tomarrow. I also need leg bands for showing identification, so if/when I get the adress I will post it.
