We currently have 7 hens and one rooster. We've raised them ever since they were chicks besides the rooster. We originally had 10 layers and gave two to a friend of ours who lost his.... They are already laying almost every night for him and we have not gotten one. They have access to food and water every day and night. The have a 11 by 17 ft pen with a two story 6 by 4 coop. The sleep at the top but have sections underneath where they have made a nest, but still nothing. They are let out every morning around 7 to 8 and go in around 7 to 8 at night and we close them in around 10 pm. We don't know exact breeds but we think they are IOA's, jersey giants and the two white ones (we gave our friends the two other white ones we had and they are laying for him). Any help is greatly appreciated because we are stuck!
