For our current (first) generation, I've been using vet wrap tape to make leg bands to identify the different birds, but it's been fairly fiddly and they tend to fall off over time and need constant monitoring to make sure they're not getting too tight. Now that the pullets have started laying and I'm planning the second generation, I was researching better tagging methods. I came across this article: https://academic.oup.com/ps/article/87/6/1052/1588223# - it looks at the effects of different tagging systems, and the ''Swiftack" option was one of the better ones. However, looking online, I can't find any reference to it outside of various scientific articles, and no pictures of what it looks like. Has anyone come across this system before? Any idea what it entails?
