☆Chicken Chaos☆
Nuthatched is so right.They absolutely can be nasty and they shouldn't eat food scraps in any moderate quantities.
Why do you want chickens?
Have You thought this through to present your mom a good representation?
They are completely different than cocketiels.
Are you prepared for 6-12 years of caring for livestock?
Is their a vet available that not only takes chickens but actually knows about them?
Are you prepared to doctor them when they need it or even put them down?
Have you checked out your regulations for poultry? Neighborhood? Town? County?
If there is not a vet, that will be on you, and I can 100% vouch that is NOT fun and very stressfull. I have successfully saved mine from dying twice. Do not take them to a vet who knows nothing about chickens. A vet almost killed one of mine.
