My BD is about 2 years old. When I woke up this morning she had laid one eggs. She has not been with a male so it is not fertile. She doesn't want to eat. I have been able to get her to drink water. She is still active. Waiting out of her cage. Her poop was really runny today. Is it normal for them to only lay one egg? From what I've read there should be alot more. What do I need to look for if she is egg bound? When should I take her to the vet?
