Hello all, First of all, this thread isnt asking for help. Im here to help anyone who has a duck with similar symptoms. Peach the white Peking Duck was approx 10 months old when she started loosing weight and excreting bright green poop. I had read somewhere on here that it was bad. Peach was a good layer. A little too good. An egg a day for 4 months straight. This led to her laying soft shelled eggs or rubber eggs. I didnt know this was potentially harmful at the time. Anyhow, she stopped laying and got sick. After a $448 vet visit bill (overnight stay with iv line and a script of antibiotics) we came home. A month later she passed a lash egg. She began perking up again after this. Fast forward another 10 months and her symptoms are as follows; Started sleeping a lot during the day, withdrew herself and found a place to hide away from human and other duck contact, was very anti social, did not like other duck or human company, was not able to walk more than 4 meters or 12 feet without a rest, lost a lot of weight and was not interested in food. She passed a small lash egg, which after inspection looked 'broken off'. I brought her inside for her final 4 days so she could rest. She refused food, and didnt like to be picked up. Her eyes where almost stuck closed. I decided it was time for tube feed, so the last 18 hours i tube fed her. Today she passed away much to the devistation of myself and my wife. Peach was my first incubated duck who was imprinted. She was a very lovely girl who was always interested in what you were doing. I have 3 other ducks and a drake, so i decided to inspect Peach to determine the problem. This was no easy decision, as we really loved her. But in the future health interest of the rest, I opened her up and inspected her internals. I found she was totally blocked up with lash eggs. There where 5 which had all gone hard. So a sad day for us here, but at least Peach could help other duck people out there.
