If you want to raise quail, building rack cages is the easiest way. Building the wooden part of the cage can be a do-it-yourself project. The one piece of the cage that needs pre-fabrication is the metal shelf liner. The shelf liner must bend up about 3 inches in the front and back of the shelf. Painting the wood with high gloss paint deters parasites and makes it easier to clean.
Paint all the parts and mark the sides for the shelves. Apply high gloss paint to all the plywood and lumber of the quail cage with a paintbrush. Once dry, place the two pieces of 3/4-inch plywood measuring 96-by-20 inches on a worktable. Measure from one 20-inch side and make marks at 13, 24, 35, 46, 57, 68 and 79 inches. Mark the end from which you measured as the bottom of the sides.
Attach the shelf supports. Place the framing square on the marks and draw lines across the plywood. Apply glue to one of the wide sides of the 1-by-2-by-20-inch lumber pieces and place them on the bottom side of the lines. Secure them to the sides with the box nails.
Install the shelves. Stand the sides on one of their long sides so the shelf supports are facing each other. Place the 30-by-20-by-3/4-inch plywood between the sides and on top of the shelf supports. Secure them through the sides with the box nails. Each of the seven shelves should safely house 29 fully grown birds.
Secure wire to the shelves and sides. Place the 31 1/2-by-83-inch welded wire on the edges of the shelves and sides that are facing up. Align it with the bottom of the bottom shelf and the top of the top shelf. Secure it to the sides and the shelves with the high tensile wire staples. Turn the unit over so the wire you just installed is on the bottom.
Fasten the wire doors to the shelves. Attach two of the 15 3/4-by-8 1/2-inch pieces of welded wire side by side to each of the openings starting from the top of the top shelf. Use the high tensile wire staples to secure the wire to the shelves, but don’t drive them all the way in. There will be a gap between the wire and the shelf below it for removing the shelf liners.
Set the feeders in place. Stand the rack cage upright and put the metal shelf liners on the shelves. Hang two feeders per shelf on the outside of the wire in the front and the back of the cage. Cut openings in the wire above the trays with the tin snips. Make them large enough for the quail to reach the food and water without escaping. Use the feeders on one side for water and the other side for food.
