I am new to the chicken world.. I acquired a rooster and two hens. My rooster is around seven months and one hen is nine months and one is around ten months. We have a coop in our backyard. We built boxes for them and lined it with straw. We have had no eggs. One of the hens that we got was laying before. we gave her a month and now she is not laying either. We do not know what is wrong. I need help..
