Do live chickens aggravate asthma? Are there ways to remove spurs from young and growing roosters?

My mother-in-law is a teacher in an elementary school and has a chick as a classroom pet. She is wondering if live chickens are likely to aggravate asthma in children.

Also, the chick appears to be growing spurs and she is concerned that when the chick becomes older that he will use them against the classroom children. Is there way to remove the spurs that grow on roosters (in a humane manner)? If so, what would something like that cost?

Thank you for your assistance.

yes they carry pet dander (DOWN) like any other bird… about the spurs I can’t tell you, because I know nothing about this sorry.
