How do i start a quail farm? Diet? Cages? Breeding? Hatching? **URGENT?

you fail to mention the type of quail you are purchasing. Depending on the breed, make sure your cage is large enough for the number of fowl you got. I always fed my quail a gamebird mix of feed, and parakeet feed as a treat. Once they start breeding and laying eggs you can hatch the eggs in an incubator and raise and sell the chicks. If you are getting baby quail, you will need to have a brooder box for them. This could be as simple as a cardboard box with a wire lid and heat source. You will need a special water font (found at most feed stores) for quail so they don't drown in the water. Food and time and patience.
