I have two backyard chickens that we inherited from my daughter's classroom. They incubated them and we brought them home when they were about 4 weeks old. I do not know the breed of either one, which isn't as big a deal as knowing the gender. They are 5 months old, and neither has begun laying. I live in city limits and can't have a rooster, so I need a little help in determining what I have. Any help is appreciated! Thank you
