How to Disinfect Chicken Coops With Bleach

Updated February 21, 2017

Chicken coops need to be cleaned and disinfected before the onset of winter to remove any bacteria and worms that can lay dormant until the following spring. One way to disinfect a chicken coop is to spray a bleach water solution to kill any bacteria in the chicken coop. Never disinfect a chicken coop with bleach until you have first removed all of the chickens, as the bleach is hazardous to their health.

Remove the manure and debris from the floor of the chicken coop with a shovel or scraper.

Spray down the floor of the chicken coop with a garden hose.

Add ½ cup of bleach and a few drops of liquid dish soap to a bucket and fill it with water.

Dip a scrub brush into the solution and thoroughly scrub the floor. Spray down the floor with the garden hose to wash away the solution and then let the floor dry.

Add ¼ cup of bleach to a spray bottle and fill it with cool water.

Spray the entire chicken coop with the bleach solution.

Let the solution dry, and then air out the chicken coop before putting the chickens back inside. You should let the chicken coop air out for at least two hours.


The bleach will break down after it has dried and will not harm the chickens.


If you do not completely rinse down the chicken coop, any left over residue left on the walls or the floor can poison the chickens. Wear gloves when scrubbing with the brush to prevent your hands from smelling like bleach.
