Hi, our beloved 19 month old Peking duck is sick. We took her to the vet yesterday and was told she is suffering heart and lung problems. We wanted to give her a chance so the vet injected two meds: an antibiotic and another med to drain fluid. He also gave us one week of pills. After three doses, the duck showed improvement this morning. However, the new challenge is to feed her because she is not eating. She is only 5 lbs now and has not eaten for 4 days. This is a wonderful duck. In her short life so far, she has laid 450 eggs. My question is to find a high energy food to feed her with syringe. We gave her some baby food (using syringe). Plus, we mixed her pills (grounded first) with baby apple source. I went to the local Tractor Supply and they did not have anything. I grounded the feed but there seem to be some gravel mixed in there so it stuffs the syringe. Thank you so much in advance.
