We have 5 barred rock girls who are now 8 weeks old. We can tell only one apart from the others as she is much darker. We would love to tell the other four apart, but they would need leg bands. We put leg bands on them when they were just a few weeks old and they went crazy, pecking at them and seeming very agitated....so we took them off. Has anyone ever used leg bands? How long until they get used to them? Our other chickens are silkies, and then we have Ameraucana's coming and two Icelandics....so they are all very easy to tell apart.
