Please could someone explain to me the differences between these colours? I am brand new to this stuff and am trying to figure out which chicks are what colours etc. At about what age can you tell for sure what colour they are going to be? I have two bantam cochins chicks and when they were newly hatched they both had blue on their backs and one had some on its head. The one looks like it may be pure white while the other one has some slight hints of blue... Anyway, if you have some pics of a good example of each of these colours it would be really helpful. At what age are they feathered in their mature colour and not just the youth feathers?
