I have a problem with the chicken poop causing a increase in nitrogen in my soil, which has resulted in the death of my cat. Dog might have the fungal infection also, will not know until visit to Vet. I need to buy some Formalin solution to spray and kill the fungus. I know it is used in aquaculture and other agricultural operations. I can order it on Amazon, but does anybody know if it is available at Tractor supply, Home depot or at a local retailer. I don't want to wait to long. This is my problem http://www.vet.uga.edu/VPP/clerk/Edison/index.php It looks like I will have to get rid of my chickens if I can not control the fungus. I live in Olmito TX, which is next to Brownsville, TX. If anybody wants 3 hens and 3 roos for free let me know. I will also throw in some supplies, feeders, waterer, feed, etc.
