Need help! Another sudden chicken death. This time on video.

So you are 100% positive there should be no blood in the abdomen just because the chicken was not butchered/bled and was dead for about 12 hours at +10C? I have examined gizzard and guts and did not find any blockages or ruptures. We do use any poisons on the property.

I've only found blood in the abdomen of one chicken that I necropsied and that was the pullet I mentioned in my previous post.
I have never found blood in the abdomen of any other bird I have either butchered or necropsied.
So, for me - abdomen full of blood is abnormal.

That is a lot of blood.

Do you feed treats often?

if you mean corn, than only before freezing nights in the winter time - 4-5 handfuls for 35 birds, why?

No, I actually mean anything besides a complete balanced commercially-made poultry feed.

they don't get ANY of complete balanced commercially-made poultry feed
they are getting protein and veggie scraps besides purchased grains and oyster shells

What are the grains?
Not saying this is your issue, but you may want to consider feeding a balanced poultry feed like layer feed to see if that makes a difference.

Maybe consider a feed change.
