Is it true that parent birds reject chicks handled by humans?
Partly. A hand-rearing reference states that human handling of a chick can cause the parent bird to reject it or abandon the nest, while a biology Q&A cites Snopes saying mother birds will not reject chicks because of human scent and calls the belief an urban legend. The sources directly disagree on the claim.
