So I just found one of my barred rock hens on the floor of coop, she’s conscious and alert. She is limping and having a difficult time moving around and she had poop all over her bottom. Breathing also sounds congested. I put her down in the run and the other hens immediately starting attacking her. She’s isolated now with food and water and I’ve cleaned her bottom. Any other suggestions or ideas? I’m thinking nutri drench and epsom salt soak.
