I received an couple of chicks from a student doing a science fair experiment, who told me they were hens. They are about 10-11 weeks old now and I have a sneaking suspicion that they are both roos. One is an easter-egger, who has begun doing a wimpy crow every morning, and the other is a tolbunt polish, who just kinda chatters all the time. I really love my little birds, but if they are indeed roos I am going to have to find them new homes, as our city and neighborhood doesn't allow roos at all I have attached pics of them when I first got them and now. I've never had chickens before, but I believe they are starting to develop spurs. Please help me verify their sex.
