I purchased 6 female quail approximately 4.5 weeks ago. The individual I bought them from said they were current egg layers, and I have no reason to doubt him. They have had plenty of food/water, are on a Purina Game Chow Growth and Plumage food. I recently put a cat litter box in their pen with dirt/sand, which they really enjoy. I've read online that it can take 2-3 weeks for birds that have been moved to begin producing eggs again. I tried my first hand at vent sexing just now, and I'm pretty confident that 2 of the 6 are female - I want to let them calm down before I try to look at more of them. What would be keeping them from producing eggs? Their enclosure has a 2'x2'x2' completely wooded box, with a 4" x 4" door for them to get through into a much larger, 5' x 2' x 2' wire pen. There are six birds, so it should be plenty of room. Any thoughts?
