She has been having this white yellow diarrhea for a few days. As soon as I noticed that she wasnt acting right or eating like normal I separated her from my other 5. I cleaned around her vent. No redness or blockage or loose feathers. She laid an egg 3 days ago, but nothing 3 days prior when she started acting lethargic. Laying on the floor alot and staying away from the others. She is normally my most aggressive hen. Esp when I feed and hand out treats. I immediately bleached both the feeders and waterers. They are currently indoor chickens and stay in a small part of a very large room. I keep their floor as covered as possible because it can get cold (linoleum). I have heat lamps abt 4 ft from the floor for heat, but the room is very large. Any idea what was wrong with Betsy??
