gander007 these are just colored zip ties. Each color represents the hen the chicks came from, it's how I keep track of them till I can recognize them. Our Society is working on having numbered leg bands made which will be for 1 yr old/older birds. Some like to use numbered leg bands and some don't, it's a matter of preference. These will be Society specific but anyone with Orloff who is interested will be able to purchase them.
I did not think of doing zip ties that is a good idea and I understand the need for the marking of the birds as I have been purchasing the expandable leg bands on e-bay but I have been unable to find any numbered leg bands as I do the same thing as you are doing marking each chick so I know which hen the chicks are from so I know which ladys are giving me the chicks I am shooting for as the standard it seems several of my ladys look great but tend to give me chicks that grow up and the hen has more white then I would like and several give the spangled and this is what I am shooting for but some people like the Orloff's with the white so I just wind up selling them .
So when I saw you were using the leg bands I just had to ask you if you were doing the same thing as I was doing and it seems so, so good luck with your breeding program and maybe someday we can do business ..
