As I continue to be given more and more pairs of peafowl, which I totally adore, I realize that I will need to use numbered leg bands instead of just zip ties. I have some colored ring bands now that are much too big for the birds I have and I can use those but for my breeding programs I usually use #9 colored, numbered leg bands to keep up with my bloodlines and write in my record books. Looking at the different birds he is giving me, there are about 8 pairs and maybe as many as 10 pairs (possibly trios). Some are the same variety like Silver Pied but also I may want to move some birds around to try different combinations and need each bird to be easily ID'd in my record keeping. These birds are from 2 years old up to 10 years old. What size do you all recommend or use?
