How to Build a Stacked Quail Cage: DIY Plans for Coturnix

Quick answer

Start with the birds, not the outside footprint. Use usable floor area of one section divided by planned birds in that section, with at least 1 ft² / 0.09 m² per Coturnix and 1.5 ft² as the kinder target. Build one square lower cage, copy its serviceable layout for the upper tier, and secure the stack before use.

Stacking saves floor footprint; it does not create free capacity. If you want a ready-made route, our stackable cage picks include a verified Hatching Time two-layer Traditional system with six configurable sections, roll-out collection, removable waste trays, and gravity-fed watering. That is complete indoor or enclosed-shelter equipment, not a DIY plan or a predator-proof outdoor cage.

What do you need before you start?

Draw one section at full service size before buying materials. Write down its length and width, frame allowance, divider and door positions, tray clearance, and the duplicate pieces needed for the upper tier. That list keeps a support from stealing bird floor or tray access.

• Floor and walls: 1/2 x 1/2 in / 13 mm hardware cloth for adult flooring. Chicks need 1/4 in wire.
• Frame pieces: enough material for two matching cage frames, supports between tiers, doors, dividers, and a braced base.
• Service parts: a sloped collection floor, removable waste trays, feeder and water hardware, fasteners, and protection for cut edges.
• Tools: tape measure, square, level, cutters, driver, and a way to check every seam by hand.

For housing basics, check Penn State Extension, Mississippi State University Extension, and Texas A&M AgriLife poultry guidance on space, flooring, and access. Then fit those checks to your own section.

How do you build the cage step by step?

Work from the lower tier upward. Plan the usable bird floor first, make the first frame square, fit the floor and trays while access is easy, then duplicate the tier and brace it. Finish with a careful inspection of every surface a bird, egg, tray, or water line will touch.

Step 1: Plan the usable floor

Calculate the floor before cutting. Use usable floor area of one section ÷ planned birds in that section. Frame, divider, feeder, and water hardware reduce usable floor, so measure the space birds can actually stand on. Keep each adult Coturnix compartment 8–12 in / 20–30 cm high.

Step 2: Measure duplicate pieces

Mark a worksheet for both tiers. Record the section floor, wall panels, door, divider, collection lip, tray path, and frame allowance. Mark the upper-tier pieces from the same layout, while leaving room between levels for the tray to slide and the lower birds to be serviced.

Step 3: Frame the lower cage

Build and square the lower cage first. Fasten the corners, check the diagonals or use a square, and make sure the doors open fully. A crooked lower frame passes its problem to the upper tier. Add supports that will carry the upper frame without blocking doors or trays.

Step 4: Fit the floor and trays

Attach the floor wire and collection pieces. Use 1/2 x 1/2 in / 13 mm hardware cloth for adult flooring, cover cut ends, and set the egg roll-out section at approximately 7–10°. Add a front lip and a removable tray. The tray must clear the frame, travel fully, and remain reachable from outside the cage. For examples of this layout, see quail cages with egg roll-out trays.

Step 5: Stack and brace

Level the upper tier before fastening it. Put the second complete cage on its supports, check that it sits flat, and brace the assembly against side-to-side movement. Keep upper doors, water connections, and trays reachable. The stack should stay still when you open a door or pull a tray.

Step 6: Test every service point

Run a full empty-cage test. Open each door, pull every tray, inspect every cut edge, and check that dividers cannot shift. Route water so fittings do not drip onto the floor or block access. Test the stack by opening doors and pulling trays; stop if the frame twists, rocks, or pulls a fastener loose.

What mistakes should you avoid?

Most build failures start on the worksheet. A cage can look roomy while giving birds too little usable floor, hiding a tray behind a support, or leaving a sharp wire end at shoulder height. Catch those problems before you close the frame.

• Counting the outer footprint. Calculate the standing floor inside each section and subtract hardware, dividers, and frame intrusion.
• Using the wrong floor opening. Adult flooring is 1/2 x 1/2 in / 13 mm hardware cloth. Chicks need 1/4 in wire. Remove or cover sharp cut ends.
• Trapping the lower tray. Dry-fit the tray before closing the upper frame. If it cannot slide out fully, move the support rather than accepting poor cleanup access.
• Skipping outdoor checks. A sheltered indoor build does not become predator-resistant by sitting under a roof. Read the predator-proofing checklist before outdoor placement.

What should you check when the build goes wrong?

Start with the symptom you can see. Empty the cage and keep birds out of the work area while you correct the frame or access problem. A small obstruction becomes a daily chore once trays, water lines, and birds are in place.

The stack rocks when a door opens

Recheck the base and upper supports with a level, then add bracing that does not block doors or trays. A frame that shifts empty needs correction before birds and water hardware add weight.

Eggs stop at the front

Inspect the roll-out slope, collection lip, and tray clearance. The floor should be approximately 7–10°, and the tray needs enough front space to sit below the lip and slide free.

The tray catches halfway

Look for a frame post, wire edge, fastener, or upper support in its path. Mark the contact point, protect the exposed edge, and reposition the obstruction before adding bedding, waste, or birds.

Water access is awkward

Move the fitting or line while the cage is empty. You should be able to refill, inspect, and disconnect it without reaching through a cramped door or leaning on the upper tier.

When is a complete system smarter than a DIY cage?

Buy a complete system when you need six configurable sections, roll-out collection, removable waste trays, and gravity-fed watering without drawing every service opening yourself. The verified Hatching Time two-layer Traditional cage suits that brief for standard Coturnix, especially when repeatable sections matter more than a custom frame.

It remains indoor or enclosed-shelter equipment, and its listing details do not replace your floor-space calculation. Choose the DIY route if your room, section shape, or access needs are unusual. Choose the complete system if the included trays and water setup save you from building the fiddly parts.
