My Chickens are dying without showing any symptoms ..Need help

[sanydhange]

I will say there is almost no fat in this bird.
Did you check the contents of the crop?

Yes . Crop only had some feed in it.

 

[sanydhange]

If no one spots anatomical clues, no injuries, could they have been poisoned?

Poisoning is possible as they are free ranging i will keep them in closed shed for a week and check

actually i am not seeing anything wrong or off with those inards. The green thing in the picture my mother called the bile. Never cut into that when you are dressing a bird for the freezer.
More helpfull information needed would be the housing and manner of area and volume of birds, what they eat, how many deaths.
if they free range, is it possible they are getting into something making them sick?

Housing is 10x10 feet shed.in morning shed is open and they free range with 60 % of feed..birds are total 74 out of which 10 are dead.now left with 64....i am free ranging them pst 5 years so i sont think something out there is making them sick
