In the summer of 2014, specifically August and September, and the winter of 2015-15, specifically December through March, Dr. Brigid McCrea of Delaware State University conducted a small flock trial with the ammonia Control product name CHICK Flic®. For the Summer trial there were 6 participating farms and in the Winter trial there were 7 participating farms. Dr. McCrea obtained permission from small flock owners in her state to determine the effectiveness of CHICK Flic® for ammonia control in their coops.
Ammonia levels that exceed 30 ppm in the coop will begin to affect the health and performance of a chicken. In commercial setting, particularly organic poultry production settings, chickens cannot be kept in facilities that have ammonia levels in excess of 30 ppm. If chickens are kept in facilities, commercial or small flock, that have high levels of ammonia for long periods of time can suffer corneal lesions on their eyes that may lead to blindness.
In all farm visits, ammonia levels were reduced after CHICK Flic® was applied to the litter, regardless of the season. CHICK Flic® was able to reduce ammonia levels significantly in two instances during the summer. The product did reduce ammonia levels on average 15 ppm during the summer and 21 ppm in the winter.
On average, CHICK Flic® kept ammonia levels 10 ppm lower than the previous week during the winter months and 30 ppm (excluding 2 extreme cases) during the summer months. This means that CHICK Flic® in the summer could be applied and give small flock owners a week of extra time before needing to complete a litter cleanout. In the winter, it would perhaps give small flock owners at least 2 weeks of extra time before needing to complete a litter cleanout.
