Helen, the pullets on the left have a black comb. I'm guessing she's currently between 4 and 5 months old. Is this something I should be concerned about? Her sister on the right, is Wanda, Wandas comb is a light color and is getting redder. Helen's is still black. Also, I'm not sure if it matters or not but we've recently been able to determine that Helen is the alpha in our small flock (we have 4).
