I have been treating my sick chicken with metoxyl for a week after the vet diagnosed cocci. She has been great all week, eating normally, was drinking a lot of water and happily following the other chickens in The garden looking for grubs etc, in other words a happy chicken but also yesterday and today her poo seemed normall again and not loose. She is also loosing a lot of feathers at the moment. We live in France and have had some lively warm weather for October, also she hasnt laid any eggs for two weeks. Today, she has been very lethargic, hardley eating or drinking and tucking her head under her wing and falling asleep all the time, she really doesnt look well so I have tucked her up for the night in her own nesting box and dread seeing if she will be alive or dead in the morning. I have no idea what is wrong with her as she has eaten and drunk the same as the other chickens and they seem fine.
