I have several batches of eggs hatching around the same time and wanted to be able to identify them by breeder. That way if I have some exceptional Silkies come out, then I know which breeder I want to order from in the future. I have seen those spring leg bands and was wondering if they would be sufficient to use. What size would I need to start with? My first hatch is 18 Silkies that are almost 2 weeks old. I'm not interested in using wing bands. Any help on size or other suggestions would be appreciated.
