We just bought silkie chicks yesterday and tonight noticed this one has two different colors on each eye. I don't know how old the chicks are, maybe about 3 weeks(the breeder had different sizes together between 3-12 weeks) They are all still peeping, not fully feathered. This chick isn't as active as the rest but it CAN stand and walk. It tends to crouch down most of the time. Is heterochromia indicative of a more serious condition? Is this chick blind, or partially blind? It doesn't tend to squint when you move your finger towards its eye, until your finger touches the feathers on its face.
