Just make sure you keep them well taken care of, most importantly poop patrol. If your mom steps in chick poo ONE TIME, you'll never hear the end of it. And the smell... you can easily get used to it by spending a lot of time with them, so make it a habit to clean everything once a day.
I wrote my dad a 12 page report on why I "needed" chickens, converted the giant dog house, built my own run out of scrap wood, and settled in 4 Bantams, 3 girls, 1 boy. And I'm 27 years old and married! Just staying at his house for awhile waiting on my husband to figure out what's next with the Army.
Working on adding 3 layers... but I haven't found any I like. I want Partridge Rock hens, to match the color scheme of the Bantams.
He brought them kitchen scraps yesterday, his way of saying "I guess they're alright"... made a comment on my building quality, and a comment on how the area smelled like pine and not chickens.
