Have you considered the spiral leg bands? Most chicken supply magazines ( and I assume online as well) have them. I got mine from the local co-op and paid 5 for a bag of 20 or 25. They come in a variety of colors so we bought two colors to mark the birds my kids wanted to take to fair. Hope this helps.I would like to band all these Silkies. I have two groups, one bred locally from show lines and one from show lines that I hatched.I would like to be able to keep them separate to control breeding (once we get there) and for ID. Thoughts?
