Ammonia Causes and EffectsDecember 01, 2017
Where there are ducks, geese, and other poultry, ammonia gas will be produced and can be harmful to a flock. It is impossible to avoid the production of ammonia, but the harm of concentrated ammonia can be mitigated if preventative measures are taken.
Ammonia gas is produced by the breakdown of uric acid in poultry droppings by bacteria in the litter. When wet, the ammonia production is accelerated and is especially prominent in coops where there is a high percentage of manure in the bedding.
According to the Occupational Health and Safety Administration, people can start to smell ammonia between 5 and 50 parts per million (ppm) depending on how well they can smell. Anything above 25 ppm and the ammonia is now in danger of damaging your bird’s health. Therefore, ammonia can be harming your birds and you don’t even notice it!
Ammonia gas is acidic and can cause serious damage not just to your birds' throat, lungs, and eyes, but your own as well. Ammonia has been known to cause blindness, damage to the esophagus, and death via suffocation. A safe rule is that if you can smell it, you need to do something about it because 1) your birds are breathing that ammonia 24/7 and 2) put your nose 6” above the litter where your birds are. Notice how much stronger it is? A good rule of thumb is if you can stay in the coop while reading a book for an hour with no discomfort, then your birds have a great environment.
You may be thinking, “But I clean my coop every day!”. If you have a small flock, that's great and you should never have an ammonia problem. However, if you don’t have time for this (and we don’t necessarily recommend cleaning every day as the build up of litter allows moisture to travel down through the bedding and away from the surface and reduces total bedding use) there are other very effective ways of controlling the ammonia.
If you are raising young birds in cold weather and have to limit your ventilation since your heater cannot keep up with the incoming cold air, there are many products to help neutralize existing ammonia that can be sprinkled on the bedding such as DooKashi, Fresh Coop, and CHICK Flic Odor Eliminator. Products such as these can be found at your local feed or pet store. We personally like to sprinkle iron sulfate in our bedding if we have a problem. It is a commercially available granular fertilizer that neutralizes the ammonia and makes your bedding even more valuable as a fertilizer for your garden!
If you can read in your coop, you're good.
