It was sugested I post here. I had noticed loose stools but a little too late. Im very new to having chickens. I got 12 begining of March. They are cobbs. White meat chickens. Everything was great until Thursday so I thought. I started seeing lethargic chickens. They didnt want to eat. They started looking un kept. Wouldn't really respond at all like before. Running across yard to greet me & follow me anywhere I went. Then a dead chickenthat evening. No evident signs as to exactly why either. Next day there was bloody stools and another hen dead. I spent the day at Tractor supply and researching symtoms. I picked up B-12 for them. The Saturday morning a rooster was acting very sick. Hes boyfriends favorite. I called local feed store. Lady there said sounds like worms. I pickd up Wazine and gave it to them. I had been gone that afternoon. I knew Hammer one of the sick roosters probably wouldn't make it. To my surprise he looked better but I lost one of the other roosters, Left Wing. This moring I was greeted by Roofus the biggest rooster with his hearty new found voice of a cock a doodle doo. All eight remaining chickens looked in good health today and very hungry. They seemed very responsive as well. I was so worried I would have to put them all down. I can't see them all dieing like that. I have a new found hope.
