Had a small flock of 3 Buff Orpingtons about 4 months of age. In the last week I lost 2 to what I now believe was coccidiosis. The 2 that died were the smaller almost younger looking of the 3 ( all 3 from same breeder in Jan of this year) All 3 have been outside in a coop and run since I bought them and were able to free range just about daily. My question is do I treat the one thriving healthy looking girl with medication? or do I just make sure she has ample probiotics, vitamins maybe electrolytes?
