My 6 year old Crested Black Swedish duck, Lucy, stopped laying eggs back in 2012 when her flock was killed off by a raccoon or fox. She was the lone survivor, I think because she passed out from fright. When I found her, she was covered in spit, blood, leaves and sand and was staggering around with gashes and holes all over her body. I nursed her ripped up self back to health and she has been a pampered house duck ever since. In all the time since, she has not laid any eggs until yesterday. And again today. I recently found myself needing to give her that abomination of feed - dry kibbled cat food - due to financial constraints, her love of the stuff, and her roomie in the next crate being a very laid back cat. I have also been adding a tsp of raw apple cider vinegar per quart to their drinking water daily. She gets chopped up fruit and veggies as they become available. Sometimes I forget to turn the lights off at night, so they will get 2 days and a night of full light. Lately she has been demanding that I stroke her back while she flattens out when I feed her. Would any of this have anything to do with her ovaries starting up again? Does anyone think it will continue for very long? Should I worry about any of this? How much calcium should I give her at this point? I hadn't been concerned about her diet and allowed her whatever she wanted because she was not laying eggs. (she loves green peas, tomatoes, watermelon and cat food) I thought she had gone through menopause (duckopause?) Any insights/advice from fellow duck keepers?
