I have 2 female Indian Runners that are 6 months old. Bonnie was sick but that night, she laid an egg. Since then, Bonnie had not been the same girl we know. She is typically hyper and spunky as she would quack a lot. She is looking skinnier and does not quack like before. Is this normal? She's laid an egg each night in her bed and I throw them away. I'm worried she will never be the same funny girl we love....Any advice will be greatly appreciated.
