Should i get rid of my ferrets?

I have had my ferrets about a month now, i keep them in a larger hutch, i have two, i feed them once in morn and once at night, they have a 1 lite water bottle so they don't need refilling much, i clean once every two days but im 13 and i don't let them out as often as i used to (about once every two days and only for like 20 minutes) is there any point me having them? it makes me feel cruel because i heard they should be let out once an hour or more daily and I just cant do it i dont know why i just never do, will they gget used to it or should i just take them back (i love them and id hate to)
