The first pic is of my GLW rooster at 16 weeks old. He was the "free exotic chick" that came with my order from Murray McMurray hatchery. He was crowing by the time he was 18 weeks old, so you may know the answer to your question soon!
I'm pretty sure she's a he. I even sent the pics to the guy I bought him from (he likes to keep in contact with buyers) and he also agreed the my bird is a rooster. Very apologetic bc he was SURE that it was a pullet. Oh well, he's going to give me a good deal on some silver pencil wyandottes next spring
yay!!
Plus I've been doing some research and if I breed him to my splash blrw I should get 100% blgw! We will see how they turn out.
