My hens (4 different breeds) are 4.5 months old. I get about two or three eggs per day, not sure who lays what! But my Australorp is skittish and underdeveloped. She doesn’t squat for me, is hard to catch, has no pronounced comb or wattles (and what she has is not red...) and in general is the loner. Is she just delayed? Or is there something wrong? This is my third Australorp hen over 8 years and the only one that isn’t a friendly little puppy of a hen. All of my other hens have their combs and wattles fully developed (Rhode Island Red, Speckled Sussex, Gold Star).
