Cockeral or pullet

[d421ja]

I purchased this pullet but I'm being told it's a roo. She is 5 months old. She acts like a hen and my male rooster is mounting her. What do you all think? She doesn't even look like my roo.

It’s really hard to tell the easiest way to tell is wait for eggs ofc

I see streamers so he's likely a cockerel
