I have a 7-8 week khaki cample duck. She has had neck problems ever since I've had her. But recently she keeps her neck scrunched up and her feathers a puffed. A week of two ago we treated her with eye discharge. Also she isn't laying down while she sleeps. We're keeping her inside alone from the other ducks/chicks. Any recommendations on how to fix this? We have possibly have 2 male ducks if that helps any. Thanks.
