To study memory loss in Alzheimer’s disease, day-old chicks were trained to avoid pecking beads coated in a bitter liquid, then their brains were examined.

It is not clear how the gradual onset of Alzheimer’s in humans can compare with the memory of a day-old chick.
What a Waste
Morphine produces a pinpoint constriction of the pupil in man - birds’ pupils are unaffected by it.
Humans can utilise a type of vitamin D that chickens cannot
The muscles of the inner ear of birds have a different reflex response from those of humans

In birds, even after total removal of the pancreas (the organ responsible in diabetes), only a temporary diabetes is produced.
The fat cells of chickens and geese are highly sensitive to the hormone glucagon - fowl are unique in that glucagon is essential for life.
