That wing patch is pretty sketch. At 16 weeks I'd expect more male traits to be visible though.Hmmmm, I would still be suspicious of it being a late blooming cockerel... it has white wing bars and kind of a funny pattern... and I personally feel that’s a lot of wattle development if it’s a pullet. My single combed pullets have hardly any wattles til they’re closer to laying age... and yeah, this bird is 16 weeks, but if there’s Brahma in there and it’s slow developing... I’m on the fence. I would be looking for evidence of shiny, pointy saddles coming in under those pretty round feathers. I’m not giving a definite opinion just yet. Lol.
Missed the age. Not so confident anymore, still not a brahma.At 16 weeks I'd expect to see some rooster saddle feathers on a male. Maybe not for a slow developer, but I wouldn't be too sure to say "cockerel" without seeing male hackles and saddles at that age.
