Rural Gardening: Oh no! My pullet's a Rooster., 1 by msjuris

On June 19th I helped out a neighbor by taking the two pullets she had bought, but was unable to keep. They are beautiful GL Wyandottes. At that time she said they were two weeks old. Now here it is two weeks later and I have a sneaking suspicion that one of the pullets is a roo.

I bought my first flock of 1 roo and 4 pullets on May 13th. I'm real new to this and have had tons of help from all of you on DG.
I have a 6' X4' coop and let them free range during the day. I had trouble getting them integrated, but they are doing well now. It just so happens that the one "Roaster the Rooster" was head pecking is the one that I believe is a rooster.

First, what do you think based on the picture?

Second, can I keep them all in the same coop?

Third, once the boys start noticing the girls, should I expect more fighting over who gets the girls?

Once again, thank you in advance for all the advice.
