II have 2 female call ducks and one of them had problems from the day I got them at 2 weeks old. This morning I discovered an egg in their cage, I'm not sure which one laid it but now one of them (Wiggles is her name) is acting lethargic and is shaking a little bit and won't do anything except lay down. She is eating and drinking. Is this normal after laying an egg ? She is about 6 months old. I read that they can be lethargic after laying. If she's not doing better by tomorrow I'm going to take her to the vet. Just wondering if anyone had any answers or opinions for me. Thanks!
