I have 4 chickens that are probably around 4-5 months old. I've thought the whole time that they were all hens but the past several days someone in the morning has started "honking" really loud. I thought I caught a glimpse of who it was today and I think it was my favorite "girl" Maude (it looked like she was flapping her wings at the same time too). She is the smallest of the four but has been the boss since day one. She also has a comb (and wattle) that's much larger than the others (theirs are almost non-existent). She isn't any particular breed - just a mystery mix. Should I be worried she is really a roo? Thanks for any responses!
Here are some photos but the most recent is probably still a couple weeks old so I'll also include a short video from this past weekend (if it will work):
Approx. a month ago:

Couple weeks ago:



This is the video (it's really short - maybe 20 seconds):
