Alot of people practice toe punching simply because it is permanent..no need to worry about bands being lost etc....it does have it limits though, there are only so many different punches you can do so depending on how many breeds you have you could run out of punch patterns. Alot of people punch birds that will be penned together...differently...problem is if you have multiple pens and they get out of the pens and another pen has the same punch pattern and the same looking bird, there is no way to tell them apart.Ok. I think I will stick to using small zip ties and small colored plastic beads. I have been using this system for 3 years. Once the bird is full grown, there is no need to change out zip ties and they are easy to see when walking around. I use different bead colors for different birth years and breeding so, I know who's who.
i personally use zipties but i have been thinking about switching to loom bands for the juvies.
