I have a flock of isa browns and leg horns. As always the best bird in the flock died first. As you may know its very distressing to wake up one day and find your best chicken lying dead on the floor. She was a isa brown and about three years old. She lost her weigh very quickly and was suffering for exactly a week. She was barely pooping, so I gave here some olive oil and that helped her poop. She was always standing and keeping here eyes shut most of the time. Her poop was yellow and green. In the fist few days here here wattles were almost white. Then they turned a pink colour before she died. Please write something below if you know what may of caused her death, and if there was a way I could of helped her.
