They don’t take much time. Five minutes in the morning to let them out and feed them. Two minutes at night to put them away. Depending on your litter style you need between 20 minutes a week or 5 minutes a week plus two hours every three months to clean out the coop. They are less work than most mammal pets. And they give you eggs in addition to being remarkably entertaining for being the closest extant relative to the T-Rex.
