My australorps are almost 15 weeks. One sang the "egg song" at 14 weeks and has done nothing since that time in terms of vocalization. My question for seasoned australorp owners is this: When do they develop their combs and wattles? Mine have nothing, although they have red on their "faces"....their combs are EXTREMELY small--like nonexistent small. My last batch of a variety of breeds of chickens had combs and wattles much earlier! Just curious...I'm really not expecting any eggs any time soon and certainly NOT before they develop their combs and wattles. Thanks for your help on this!
