Chickens slowly dying off one by one

[Immrya]

Hello. So I have a head scratcher of a situation. Last fall one of my Vorwerk hens who at the time was 6 months old, started acting more dull than the rest of my flock. No other symptoms noted. She never got any worse, was always the same dullness you could say. She eventually passed in her sleep 4 months later. About a month or so after she passed another one of my Vorwerk hens started acting the same way. I found her passed away today ( about 4 months later). My Vorwerk rooster is now acting like he's next. I have one more Vorwerk hen (they are all siblings) who is still perfectly fine, along with my other different breed hens who have not had any issues. It's very odd as I cannot seem to find any other symptoms to go off of. Poop all appears fine, they all would still eat and drink just not as fast. I have fresh water every day for them. They are on Purina flock raiser, oyster shells, lettuce to pick at and I give them scratch grains and meal worms as treats spread around the run daily. I do have the hen that passed away today on ice to bring to the diagnostic lab for necropsy but figured I'd post here of anyone else has had a similar issues. Thanks!

Welcome To BYC

I'm sorry for your loss.

Hopefully you'll receive more information from the necropsy.

Sometimes hens don't live a long time, they can have reproductive problems. Some things may be genetic.

You mention your rooster is showing a slow decline. Is he eating slower? Have you check the crop to make sure it's emptying, how about worms, have you had a fecal float?
Any lesions or canker inside the beak?

Sometimes giving too many treats can lead to Fatty Liver disease, but wait until you get your results back in. If there's indication of liver disease, then cut back on the extras to 1-2 times a week.
