They are a bout 9 weeks old, my Brahma and Buff Orpington, I noticed the BO's eyes getting a dullish blue gray color! She is active walking, jumping, flapping and seems fine. But the chick she lives with also has the same color eyes! The Brahma and BO are completely different breeds, is it a genetic thing? I have no idea if they were vaccinated when they were little. Should I vaccine my other two chicks? My hens? Help!
