The last day or 2 one of my barred rock hens has been lethargic looking and really fluffed up. She just slowly walks around doesnt eat or drink much that ive noticed. The last 3 days shes layed double yolks, but ive also noticed she hasnt been roosting at night with the other birds. Instead she perches a couple feet above the ground on a feed trough. Today i found some pretty nasty poop that i can only imagine is hers... anyone have ideas? I do have corid on hand but want to know what I'm treating before usimg it or a wormer.
