I noticed the other day that my rooster's feet kindof had a bit of bright hot pink between the toes and up the "ankle" area - and I figured he had probably found something colored and scratched at it. Today I noticed that his yellow legs are starting to get this hot pink/almost red coloring to them. It's kindof speckled, not solid, but now it's all up his legs. He is also starting to get spurs. I can't tell that they look scaly or "off" in any way except the coloring. Do RIR legs change colors as they mature?? Or is this a sign of a problem?
