Last Duck In — Duck House Night Check

Last Duck In is a short decision game about the end of a duck keeper’s day. Across four practice evenings, you count the flock, secure the house, deal with feed and standing water, manage footwear and shared equipment, and decide what to do when a bird is new or returning. Every answer is followed by the reason and the official or extension guidance behind it.

It is a rehearsal, not an inspection. A perfect score cannot prove that a real house is predator-proof, that a flock is free from disease, or that one routine fits every property and country. The point is to make a few easy-to-forget checks memorable, then send a keeper to the fuller tools and guides when the real job needs detail.

Count first, then close the night house

The first evening starts with a headcount because a closed door is not a successful close if one duck is still outside. The game then asks about the door latch and the material over an opening. These are not invented game obstacles. Poultry-predator guidance from eXtension, University of Maryland Extension and other extension services repeatedly puts secure night housing first. It also distinguishes hardware cloth from chicken wire and warns that raccoons may open a simple latch or reach through weak wire.

The game deliberately does not claim that one mesh size or one latch design defeats every predator. Local wildlife, the size of every gap, the roof, floor and fence base all matter. Use the duck predator guide for the wider inspection and the housing calculator for published space references; neither replaces looking closely at the structure in front of you.

Feed, water and wild-bird contact are one boundary

The second evening treats a feed bin, a feeder and a puddle as connected decisions. Closed feed storage discourages rodents and wildlife. Covered feed and water reduce opportunities for wild birds to share the flock’s resources. Standing water can attract wild waterfowl, even when it looks too small to be a pond.

Those choices follow the USDA APHIS Biosecurity Workbook, GOV.UK prevention guidance, Virginia Cooperative Extension and the University of Minnesota Extension. They are presented as prevention routines, not as a claim that a covered feeder makes infection impossible.

Keep a clean side and a used side

The third evening is about movement. Dedicated footwear stays with the bird area. Borrowed or shared equipment does not come straight in. Non-essential visitors stay out; necessary visitors follow the keeper’s clean routine. The exact setup can differ — disposable boot covers, managed footwear and correctly maintained disinfectant procedures are not interchangeable in every situation — but the underlying idea is stable: people and equipment should not casually carry material from one bird area to another.

The choices are based on USDA APHIS, Canadian Food Inspection Agency, GOV.UK and extension guidance. For an actual flock, work through the duck biosecurity checklist. It preserves the source-by-source detail, geographic labels and reporting links that a fast game cannot fit on one card.

Why the game gives no single isolation number

The final evening covers a new bird, a duck returning from a show or sale, and spilled feed. The honest common answer is separation with separate equipment before birds mix. The sources do not publish one universal duration: recommendations differ by authority, circumstance and jurisdiction. Last Duck In therefore refuses to turn that disagreement into a made-up “official” number. The result card says that sources differ and points back to the checklist, where the published ranges are shown separately.

That same restraint applies throughout the game. It does not diagnose a sick duck, identify a pathogen, approve a building or calculate risk as a percentage. If a duck is unwell, injured, has trouble breathing, cannot stand, stops eating or drinking, or otherwise worries you, contact a qualified avian or farm veterinarian. Follow the animal-health reporting rules where you live when illness or unexplained deaths may be reportable.

How the score works

There are twelve decisions. A correct first choice earns 100 points, a second attempt earns 60, and a later correct choice earns 30. Completing all three checks in an evening adds 100 points, making 1,600 the maximum. A lower score is not a prediction about a real flock; it only records how many tries this practice round took. Wrong choices stay on screen with a short explanation so the useful part is the correction, not the penalty.

The best score is stored in this browser by the Quackoria player. It is not posted to a leaderboard or attached to an account. Clearing site data or using a private window may remove it.

Turn the practice into a routine

Use the game as a memory prompt, then record what actually happened in the Duck Flock Journal: the date, bird count and any change worth remembering. The journal stores only what you enter and does not diagnose the flock. For the full prevention pass, use the biosecurity checklist. For building plans, use the housing calculator and inspect the real house for gaps, latches, roof, floor and digging access.

Last Duck In is intentionally a small game. It teaches one keeper habit that Quackoria’s runners, match games and flying games do not: finish the day by stopping, counting and checking.

About the game

Last Duck In is an original Quackoria decision game about one practical keeper skill: finishing the day with a deliberate night check. It has four illustrated evenings and twelve choices covering the flock count, secure housing, feed and water boundaries, footwear, visitors, shared equipment and birds entering or returning to the flock.

The factual cards are drawn from the same USDA APHIS, Canadian Food Inspection Agency, GOV.UK and university-extension sources used by Quackoria’s biosecurity and predator tools. Where authorities publish different isolation periods, the game says that they differ instead of averaging them or inventing one universal rule.

Nothing is sent to Quackoria while you play. The parent player receives only lifecycle events and the score used above the game; the best score stays in this browser.
