I have 14 hens and 3 roosters. Some of my hens are older and most of them are young and should have started to lay already. I have a 5-year old Rhody rooster and I hatched five and two were roosters. All the roosters seem to get along fine since I hatched and hand raised the two young roosters. But my hens are not laying. They are fed a variety of of grains, vegetables, bugs and grasses, etc... Can anyone assist with my question?
