Is it possible for a 21 week old hen that was fed medicated feed until 18 weeks to have concodis? I have 3 21 week Buff Orpingtons, 2 17 1/2 week old white leghorns and 1 17 1/2 week Salmon Faverolle. My Buffs just started laying eggs a couple weeks ago. It started with just one egg, then I had a few days with 2 eggs, then a few days back at 1 egg and now back to 2 eggs, so I’m not sure if all 3 are laying. Yesterday 1 of my buffs just wasn’t acting right so I kept checking on her and she continued acted differently. So last night I brought her in the house to keep an eye on her. She had runny sort of bloody poop once. I gave her a warm soak in the tub and turned on a heater for her. She has had 2-3 more small poops with a little blood. She doesn’t act normal at all. She just stands in one spot basically and looks to be a little fluffed up and sleepy. She is uninterested in food and water or even grass which they love. What does this sound like?
