I am new at this forum and relatively new with chickens. I bought three hens from my neighbor and a rooster from another fellow. Now one of my hens is acting funny. She stays hunkered down and isn't real active. She's eating good and getting plenty of water. Her poop is kind of runny and lime green. What should I do to her? I don't want my other chickens sick. Most people around here don't know much about chickens and the vet is too expensive. I have read some other posts about green poop, but mine isn't laying around or falling down. She acts rather normal except she's not perky like she was and her poop is green. Any help would be appreciated.
