Hello! I'm new at this and have had my 2 production reds and 2 black australorps for 11 weeks(we got them all when they were a day old) and 2 EEs for 10 weeks. We purchased all for egg laying only. I noticed weeks ago that one of my australorps has a bigger comb than the other and has wattles that the others don't currently have. Now one of the EEs has a bigger comb than the other, but no wattle yet. I am pretty positive that the australorp is a roo.. but I was hoping you all more experienced ladies and gents could help give me a yes or no to both of them. Thanks!
