I was hanging out with my young ringnecks today and I noticed that they have different colored legs. Some are pinkish, some are dark gray, and one or two have very blue legs. Looks like I have both males and females with each leg color. What does this mean? Will they be different colors as adults? They all look pretty similar with only slight differences in their feather color/pattern. Any ideas? I bought them as a group from a gamefarm for $0.15 each at a day old.
