Our vet called and said that my 4 year old Australian Cattle Dog has a positive for toxidia. He is not concerned about the dog if the toxidia came from our chickens... but wanted us to know it was present. I have researched toxidia and found it is coccidiosis in the chickens... all mature layers, 2 - 5 years old. The hens had this one other time and I fed them the medicated chick feed and got rid of the parasite. I am reading that cottage cheese will help the dog and may help the chickens. Anyone ever try this method of treatment?
