Senses in Poultry, by Dr. Clive Dalton


"A group of genes that code for odor receptor proteins is dramatically expanded in the chicken genome a finding that appears to contradict the traditional view that birds have a poor sense of smell.

And, as it turns out, birds might not have such a great sense of taste. When compared with mammals, chickens have a much smaller family of genes coding for taste receptors, particularly those involved in detecting bitter sensations."
