I am new to raising chickens. I have 10 in my flock. I have 6 older hens, 4 are laying, 2 should be in the next 2 months. 1 rooster, and 3 chicks. I am not sure if the chicks are hens or roosters. 1 is a rhode island red, 1 barred rock and 1 golden buff, I am pretty sure the buff is a hen, the other two, I am not sure. Any help would be appreciated .
