I have 2 5-month-old Black Australorps that I just got a week ago. I am trying to figure out how sexually mature they might be. Hen 1 has a rosy comb and biggish wattles. Does that mean she may lay soon? (She doesn't squat yet). Hen 2 has dusty looking pink comb and small wattles. Will 2's wattles grow? Is ashy pink a healthy color for a pullet's comb? Will it turn red? Thanks!
