Chickens are dying one by one. Please Help!

[SleepyChickens]

If your neighbors are also looking chickens you might want to think that someone poisoned them.
Or gave them treats that they shouldn't have ?

I also thought it's possible they got food poisoning from eating something. Is there any common symptom for food poisoning in chicken?

Food poisoning or other toxic exposure produces imbalance, lameness, weakness, and paralysis.

Gnats or black flies in large groups have been known to suffocate chickens inside coops at night.

is there any specific sign for bird flu?

It is here at the moment and the govt have issued this, which you might find helpful:

Thank you. I liked it because it is helpful, then realized it might look like I thought it was the OP's problem. I have no ideas about that.

I hope you find the cause and that it is easy to fix.

Tomato plants are toxic. Can you set a camara near your roost bar to monitor them at night?

So sad. I hope you can figure it out. Did you try putting in a trail cam to see if something is getting in the coop? I use a Ring cam that connects to my wifi to watch them at night and what area doesn’t have Wifi I put a trail cam and check it if I see anything out of sorts in the AM.

The birds all show signs of being suffocated or poor circulation(heart attack) which makes me lean towards it being a snake after chicks or eggs. 3 of the deaths could possibly be due to the roosters trying to defend the chicks, broody hens and pullets.

I've dealt with non poisonous snakes killing pullets and cockerals. The snakes would come at night and constrict a pullet or cockeral, but the birds were too big for the snake to swallow the bird.
The next morning I would find one or two dead birds outside one of the coops. Their heads and neck feathers were wet where the snake regurgitated the birds. It couldnt swallow the birds because they were too big to swallow.
I went out early one morning and found the snake. It was a yellow rat snake. I've lost chicks to these snakes as well. Fortunately, I havnt dealt with poisonous snakes.

Snakes also leave little to no signs of attack or than the purple comb.Some will have saliva on their head or have a wet head.

My suspicions are you have a very hungry snake that's eating eggs and trying to eat your chickens. One way to find out is to stop gathering the eggs. If the snake gets its belly full it'll stop killing your chickens.
