Second pic has roosters (far left and bottom birds) and the hens, respectively. Birds hatched 7/4. Pic taken 8/3. If I had to guess, I would anecdotally guess rooster for your little one.
Third pics and beyond are the same birds today…about 2 months and 12 days old. Comb size seems to become...
They are tougher to sex, especially if you only have one. I have some pics from my 5-6 week old AC. I’ll post them in a few. I ended up with 2 roosters and 2 pullets.
