I have three different bloodlines of the same breed hatching on the 23rd. What is a good way to tell them apart. I do not want to inject anything into the shell to afraid I might stick the chick or break the egg. They are all BB Red gamefowl so they all should look like chipmunks. I think they would be hard to dye after hatching. I thought maybe small tie-wraps on the legs if it would not hinder their movement, or try a non toxic black marker on a brown area of the chick.
