hen growing spurs ?

Thanks everyone for your comments. I must admit she has got quite thick legs. I was told by someone that their comb and wattles growing larger was the 1st sign of a cock,but maybe not. How old are the babies in the photo goodegg?And is the one you think a cock showing any signs of aggresion?
Someone commented on the bird on the right(sorry can't your name) that's supposed to be a hen partridge wyandotte and my partner thinks thats a boy because of the bright coloured feathers. At this rate I'm going to have to get rid of them all. Sigh, I can't believe I've been so stupid.

Ah thanks Kit Kat I will and do enjoy them, we all do. If they do turn out to be boys I will try very hard to find them a home rather than return them to the seller. I don't care about the money, just about the upset I've caused my family and myself.
 Thank you again for everyone who has replied or taken the time to read a problem shared etc. x
