HAahaa-- I have oodles of zip ties, in many colors. Used to id individual chickens for various reasons, or marking a specific breed with close look alikes. Flouresent green and yellow look too much alike so I use them as the same color.We use colored plastic zip ties. You can get a bag for a few dollars of mixed colors. Clear can also be used and they are a little cheaper. If the colored is used just pick a color for the year, if using clear. Right leg - 2013, left leg 2014, both legs 2015, then you could double band for 2016 if you keep breeders that long. Walmart, Lowes and Tractor supply all carry the colored zip ties
Come in many sizes. ANd I cut with nail clippers. THis is for chickens so far.
