My flock is now almost 11 weeks this coming Sunday. This past week we realized for sure our little Australopr is a Roo as it started to crow Now my Silver Laced Wyandotte I'm wondering about. No crowing yet but its huge and its bigger than the other SLW I own. Here is a pic of it.... The one in question with the Roo Australorp The one I'm positive is female... And for the cochin. Again no crowing and I have another cochin to compare it to. Both are similar in size for now but one has a much larger comb than the other. Its behind my RIR but this is a better shot of the tail feathers. Funny thing is even if these are Roo they are much better than the Australorp and that one is the one running the show. He protects the girls and has always been a little more skittish/flighty. He can stick around provided he stays nice and so far so good. Thanks in advance!
