I am new to chickens. Mine are 24 weeks old. They were on medicated start and grow for the first 19 weeks of their lives. I learned about feed, deep litter, egg laying and read up on the most common diseases. We have taken the best of care of them. We spent almost 2 G'S on coop and run. Now one of them is pooping mucous with blood flecks in it. Don't know for sure if its Cocci or not. Started her on sulmet today. She won't eat or drink so I have been force feeding AND hydrating her all day. So now I am just waiting.
