I recently got 6 chicks who are now 9 weeks old. In fact, my brahmas in question are 10 weeks old, I have 2. One of them has a 3 pea comb (is that what it's called) & a black long curved feather. The other had a single comb, and the tail feathers are pointy. Any advice would be lovely!! Cheers!! above photos are the single comb and crazy tail feathers is this a roo??
