This is my first flock and all my hens are between 3 1/2 - 4 months old. We have 2 Rhode Island reds, 1 black sex link, 1 golden sex link, 1 cuckoo maran and 1 Ameracauna and 1 rooster. They have a coop that has 6 nest boxes in it, and three perches. They sleep in the perches at night except for the rooster who sleeps in a nest box. I thought we would have eggs by now but nothing. Am I doing something wrong?
