I have noticed that my gold lace wyandotte's have lighter combs than my dominiques. We tried to look at the skin of one and could not see much of it due to smaller feathers but what we did see did not show any kind of mite or lice, they do not itch or preen more than the others. The rooster has some odd white streaks in his wattle (is it called that? ) So I am new to this, I heard that a lighter comb is sign of illness or parasites, they seem ok. Is this true? They are young, bought as chicks Feb. 7. Thanks!
