I went out to see the chickens this morning and I noticed our female leghorn, less than 8 months old, is sick. She is usually very active. She is standing off by herself, her poop is watery, she's not eating and is lethargic. She was fine yesterday. We had her in the back yard (the dogs were put up and they were supervised) and nobody saw her eat anything weird. None of the others seem sick. She is drinking a lot of water. I noticed with any other chickens we had that died, they were by the water bowl when we found them and that's were she's sticking. Should I keep letting her have water or take it away. I'm wondering if she might drown herself if she drinks too much. Kind of new to the chicken thing. I have her separated from the others right now. Could it be she is backed up. She is a big eater and seems to me like she's very big. She is at least 9 pounds, probably more. Any help would be appreciated. My daughter is going to be VERY sad when she gets homes. Hoping we can help Eggbert. Thanks.
