We have 5 Japanese quail, 4 hens and 1 roo. 2 hens are 12 weeks old, 2 are 6-7 weeks old. We are getting concerned because not one hen has produced an egg yet. We have oyster shell in their enclosure, which measures 4' by 1.5' with an elevated feeding area and elevated sandbox area. they have multiple hiding places within the enclosure, no signs of stress. In the mornings when we turn the light on in the enclosure (birds are kept indoors) they chirp away and hop around. The light we have is a full spectrum 5000k cfl. Feeding them on 25% gamebird feed and they get grass clippings every day as well as live grasshoppers and crickets once every few days. I dont know what we might be doing wrong. help, please!
