He is not small. His name is appropriately "Big Boy". He is much larger than all of our other chickens by far. Here is another picture of him at 15 weeks.
Thank you for the info and identification. We didn't get him from TSC, like the EEs. He came from a friend or a friend. Nice to know his true identity known now. Thanks!
Thank you for the answer. Actually got them at TSC in April. Was hoping for pullets as we already have a beautiful ayam cemani (I was told) Rooster. Also 16 weeks old.
