We have 3 Female Ducks Pekin, Crested White and a Harlequin Welsh. The were born June 28th and are almost 6 months old. Most things that ive read is that they wont start laying until spring since they are out of season. But my Pekin this morning is contorting her body, lifting ad shaking her tail a lot. i can see in her back end when she lifts her tail expanding and contracting the opening in her back end - the cloaca? Is this a sign of egg laying or could something else be wrong? Shes eating and drinking fine as well as going to the bathroom. I tried researching this but am coming up empty any help would be great!
