Rooster?

[snakelife]

I have Two chickens one is a Barred rock and one is a buff Orphington for the past few weeks I've thought my Orpington was a female Until she started making really deep noises I can't Tell if she's crowing but she sounds like a rooster. She's almost to that age where she should be egg laying so I'm not sure she's turning into a roostet or not she's at least 18 weeks old. There has been no real crow yet but I was sitting outside today and I heard something like I haven't heard before other than the normal click or peep. Attached is a video of her clucking it's just the cluck but I can't tell if it's a rooster cluck or just a hen cluck these are my first two chickens so I don't really know what to expect from a rooster or a hen For that matter

It won't let Me upload the video of her. I will post some pictures of her she looks that she might have a rooster tail.

Won't let Me upload the pictures either is there a certain age they should start crowing. I can't tell if there's any spur growth yet but I know they don't have very big spurs in there first year of life
