Hello, I'm getting worried about my Muscovy ducks. I've not had a lot of luck with them so far with very few eggs and when two girls sat, their fully formed ducklings all died in the eggs. I've not had ducks before so don't know what is normal. They free-range in a paddock, have shelter (which they never use) and access to a small pond (which they no longer use). They have been moulting...there are feathers everywhere, and I noticed that when they moulted in spring they lost a bit of weight. I'm sure this is normal, yes? But two of my ducks and the drake are looking really underweight even though they have access to feed and water. The drake in particular seems to have stopped looking after himself and is dirty, whereas the girls are all clean, and I've just watched him rushing about in circles in a really agitated way. This is not normal behaviour for him - he's usually very laid back. I've no idea how old he is. Any idea what might be going on? My hens are fine.
