None of my poultry are laying, can anyone tell me why???? I have about 30 hens, 5 guinea hens, and one duck hen. All of them are healthy, and they have plenty of roaming room, I know they aren't hiding them because I scoped out our hole property and didn't find anything, then I had someone else do it. They have food and water. And I just don't know why they aren't laying. Any suggestions?
