Agreed, there are a lot of cockerels in those photos. At least one pullet.I see a lot of roosters.![]()
For roosters, look for bigger combs and wattles, pointy curving, shiny feathers by the tail and pointy shiny feathers on the neck.
The last picture is a pullet but I don't really see another one in these pictures. It's hard to tell for sure, though. If you post pictures side and top pictures of each individual it would be easier to tell.
