That does appear to be cockerel. Roosters typically begin to crow around the same time a hen will lay, so 20-30 weeks depending on breed, but some will crow much earlier and some will crow much later, with the age gap being wider for roosters (rarely a male may crow as early as just a few weeks or as late as a year of age).
Reall, oh man was hopping it was a hen. I saw a lot of pictures online that looked the same way and they were hens. Let's see in four more weeks at age 12 weeks. Browny's comb size has stayed the same since 5weeks old.
All our hens stay with Browny, and if a hen gets separated from Browny they go crazy trying to get back to Browny. The hens don't follow the rooste, but they listen to him, and when "Pollito" our rooster will not challenge Browny, and Pollito is about 4 monts old and Browny is only 2 months like the other chickens
We have ten chickens
Five are 8 weeks
Four are 12 weeks
Pollito is about 20 weeks Bantam Rooster
