On this last picture the purple at the tail is fingernail pollish that my wife dabbled on there to tell them apart for naming them. Hopefully this helps!
Looks like you might have one hen there, but the others do look like roos. Get pics of each individual bird from the side close enough to see from head to tail. I am sorry if you thought they were hens.
X3, it looks like you unfortunately have mostly roosters... if you can get clear individual pictures of each bird from the side, there are four birds total?
There is no question that the bottom (with the fingernail polish on the tail) is a rooster. Can you get some better profile shots of the birds in the top two pictures?
ok here are the profile shots of each since a couple of you asked. I feel duped since the guy knew I wanted layers/pullets. He must have just seen that I didn't know much and pawned them off on me. Unfortunately I can't have roosters in my neighborhood so now I have to figure out how to get rid of them and not lose too much money on the deal. Thanks for all the help everyone!
The one in the top pic might be a pullet, the one in the second pic from the top looks like it's probably a pullet (I can't see the comb and the wattles on it for better confirmation), but the bottom two are definitely cockerels.
