I got these two chicks from a friend. They're 10 weeks old tomorrow, and have been crowing since they were 2 weeks old! I'm not convinced that one of them is a roo, though. This one is the odd one out. I thought it was an Araucana at first because it doesn't have a tail stump, but it finally grew about 3 long feathers a bit off-center that look like a tail. I'm pretty sure this one is a roo, and I'm worried it may have some sort of genetic or heart problem due to some issues it had when it was tiny. This is the one I suspect could be a hen, even though it crows very nicely. The comb is very small, and there are no wattles. Thanks to anyone who wants to help me guess!
