Different symptoms in all birds that are sick

[Altairsky]

Unfortunately ducks are not what we can manage, they are way noisier then chicken,

Muscovy ducks are basically mute, the only noise they make is hissing.

Unfortunately ducks are not what we can manage, they are way noisier then chicken, and we live in a small 7000 sqft plot, so our neighbours already want to k*ll us because of the roosters I wouldn't want to make them more angry.


Will do. Thanks again for your time and knowledge, I really appreciate it!

UPDATE #2
Necropsy is done, received the documens today. 2 different version of Marek's, plus Coccidiosis and Osteoporosis... just to make it easy...

I'm absolutely not surprised, but knowing this I'm surprised I've only lost 15% percent of my flock, and it seem to have stopped, though I keep in mind it can continue later on. It also more or less explains why my 33 week old marans pullets are not laying (though the now 28 week old silverudds and the only legbar that's left started to lay the last couple of weeks.)

I spoke to someone who said whatever I read around the internet, Marek's can be inherited, and is going down to chicks no matter how I sanitize the eggs. And now I have no idea if I should or should not give away eggs in the spring...

Thank you for the update!

I have read that Mareks is spread through dander, but not through eggs that have been properly sanitized.

As a practical matter, I can't think of any way to have a flock with Mareks, then give eggs to someone without giving them some dander too. Even if the eggs are clean, there is the container used to transport the eggs, your own clothes, and so forth. So I might not want to risk it, regardless of whether sanitized eggs should be safe or not.
