I haven't had a lot of experience keeping chickens but I have long experience dealing with poop. I have three big dogs and do dog rescue fostering on a small suburban lot so dealing with poop, urine and various organic smells is a daily experience. In the past, summer heat was very challenging. Agri/Tec makes an multi-enzyme concentrate that you mix with water and spray on surfaces called Abate (XP) that is environmentally sound and safe for living creatures- kids, dogs, chickens, fish etc. It alters the poop and urine and eliminates ammonia. Ammonia can be a big problem to breathe and is not good for chickens (or anyone). Flies love to lay larvae in poop and, though your chickens love to eat the larva, the neighbors will not love you for breeding flies. Abate (XP) works. Fly larvae doesn't hatch. The chicken coop and run is just outside my bedroom window and MUST smell fresh. It works on dog dander smells in carpet, garbage bins, kennel runs, and yards. They use it in zoos and any place that organic odor is a problem. It is supposed to be effective on skunk odor but, thank goodness, I have not had to try out its effectiveness there.
This is my first post. I have been mostly reading for information but I just had to share my discovery of this great product. I think they may advertise on this site. I live on the gulf coast near Pensacola and am on my second try with raising chickens- this time with the right set-up. The flock consists of 2 Delawares and 2 Rhode Island Reds one month old and soon to add two Australorp pullets from a local breeder when they are old enough to sex.
