Haha I feel ya! I wouldn't get rid of them yet. People have been surprised before thinking they had little roosters but turned out to be a hen.
Do you only have these 2 chickens?
If so, I will throw some advice... if you end up with 1 cockerel (young male) and 1 pullet (young female), make sure to get more pullets. The ratio for cockerel to pullet needs to be much higher. I have 1 cockerel and 11 pullets. That way the cockerel doesn't harass and over-breed the pullet. She could get hurt. Or just get rid of him and keep only pullets.
