I know it's early, but this little one is feathering very slowly. My dark brahma had much bigger wings at this age. I see 3 lines in the comb already under the fluff. Plus, this little one is so very friendly. He/she is about 10-11 days old Any guesses? I'm secretly hoping for a boy. This little one was in the pullet bin, so I'll give him/her a few more weeks. Here's my dark brahma last year around the same age or a couple days older.
it is really early as you well know but it does kinda look like my little boy. I started noticing that he was different then his sister at a week old. His sister had a little longer wing feathers and they made a more rounded shape. His were really short like in your pic and they were more square shape. I knew for sure between 2-3 weeks because everyone was feathering and he still wasnt a least not like the rest. He is now 5 weeks old and all of the girls have all of their feathers in and he is still trying to catch up
