All chickens have those Studio2770 but in the males they are longer and pointier. You can also look at the hackle feathers which will be similair to the saddle feathers if they are male. Another pointer is the size of the feet. Compare these to the feet sizes of your other birds.
They have a more upright stance , larger feet and their tails are going roostery. Im not sure about beast being a roo though or pip as i have not had close ups and pics on their own
