I have noticed that after we hold some of our chickens we have what look like dandruff on our shirts. If I look at their feathers at the base, it seems like there is dandruff there too. Also noticed today that one of the RIR rooster combs looks dry (like when you look at your hands in the winter and the skin looks dry). Is it possible that they aren't getting enough fats in their diet? They're nearly 6 months old now. They're transitioning from chick/grower feed to Layena. Any thoughts? Do I need to do anything? Is this just from molting (the apparently dry skin) or is this a symptom of something else? They all seem very healthy and robust.
