Budget-Friendly, Fire-Proofing for Barns, Poultry Coops

Look for metal, food-grade drums with airtight, watertight, and fire-resistant lids. This will help prevent the highly-flammable grain feed (high oil content) from feeding any fires.

Used metal sheeting/fencing can be repaired and repainted to be used overtop any wooden walls, floors, roofs or ceilings.

Install fire-safe doors.

At least four feet wide, 2 feet deep, immediately surrounding any barns, or poultry coops can be fire-resistant landscaping:

Gravel
Construction sand
Rubber mulch
Reclaimed bricks
Reclaimed tiles

Those can also be used as interior flooring, instead of wood.

Install a high-pressured, indoor sprinkler system, activated by smoke and explosive gases. It has to be connected to an adequate water supply. The well water levels needs to be able to supply the system with enough water to run on high pressure, to cover the entire interior space, for at least three hours. This also needs to be connected to a reliable, backup power generator, located to run safely outside, for at least three days, in case of severe blizzard power outtages.

Security fencing (metal, lockable), with wireless exterior security cameras around the perimeter will help to prevent vandalism and arson. Motion-activated, bright lights can also help deter bears, and criminals, including arsonists.

Use fire-resistant heat lamps for brooding chicks or ducklings.

Have your furnaces, woodstove chimneys maintained to prevent leaking gas or oily soot fires.

Keep at least five full-sized fire extinguishers accessible outside of the 1,000 square feet + barns and coops, in bright red-painted, metal, fireproof, weather-resistant lockboxes.
