Hj, I acquired 2 'Aylesbury' rescue ducks from an animal sanctuary last autumn. (I think they might be cherry valley). Anyway, a few months ago one of my girls starting limping, worse when she got up but got better as she moved around. I thought old age and perhaps arthritis, no obvious injury to her foot or leg. More recently she has been wing twitching a lot, it looks involuntary but sometimes she is still and I have now noticed bleeding from her nose. She spends a lot of time just sitting in the water bucket or just sitting in the coup. I am only getting one egg and assume it is her that is not laying but I always find the egg where she sits. I wormec them a couple of months ago with flubenvet and once a week put a poultry drink in the water. They mix with my chickens and eat layers pellets. Any ideas please? I want to get more ducks but worried this could be a contagious disease.
