I had my bantam leghorns running together and decided to hatch a few eggs. There was one of eac lt brown and white roos and 2 white hens and 3 white pullets. All were laying. I hatched 4 chicks and they were all white. Now at 2 weeks there are 3 that are getting some patches of light brown on them and one that has a bit of black on the wing. One is pure white and is smaller than the others. It kinda seems like the colored ones might be boys brecause they are all bigger. Could they be sexlinks?
