Need some help with sexing this chicken.

[Lay-A Organic]

Hello fellow chicken owners,

My RIR rooster and my RedOrpington hen got together and had a beautiful chick. Now that it is about 13 weeks old I need advice whether you all think it is a Cockerel or a Pullet. It has a few characteristics of both. I is pretty friendly and like to be held, but it maintains eye contacts and constantly harasses my two other pullets. I Has a couple of pointed saddle feathers and has a slight slope to its tail, but it also has mainly rounded saddle feather and since it is a orpington RIR combo its feathers can both be naturally shiny and sloped. I need your help! Here are some pictures:

It's a cockerel for sure.

Those Shiny, sort of crosshatch textured feathers tell me that's a cockerel
