My kids do quite a bit of the maintenaince on the chickens, however, if you are looking at getting them, and your parents are not willing to be at least be minimally involved, I would not do it.
Chickens are not like cats, where you can just sort of ignore them, & when they want something, they let YOU know... instead, you need to be watching for possible issues on a daily basis.
It may only take 15 minutes, but it's a very important, and very DAILY 15 minutes.
Also, the more time you spend with your chickens, the funner they are! They will get to know you, they will enjoy your company, & you will enjoy theirs!
