We became "chicken farmers" six months ago when we purchased 5 chicks (that were all "sexed" as hens) and 7 more chicks 4 weeks later (all hens as well). We never questioned gender until this weekend when one of our eggs (only one hen is laying so far) had a spot of blood in it, which I am told indicates a fertile egg. We have NO crowing, NO aggressive, NO spurred, NO really different looking chickens and don't know how to identify the rooster. We have removed the one with the most developed comb and wattle (which we had believed to be the hen laying the eggs since it is the only chicken we have seen in the nest. They have all been fairly slow to develop, and we thought that if there was a masqueraiding rooster we would have known by the time he was about 10 weeks old....we are perplexed. Do you know if this is a hen or a rooster?
