Every so often, you need to do bigger chores, like go buy fees or fix something in your setup. A couple times a year you need to do a deep clean of the coop (throw out all the straw, scrape any poo that's collected on the floor or wherever, put in clean straw). Sometimes a chicken dies, and that's not fun, but it is something you have dispose of properly.
Ultimately, though, it's a hobby. It should be fun or relaxing most of the time or else it's not worth it. Like gardening or running a home server. If you're trying to just save money, maybe you can save a tiny bit in this particular moment, but there are surely better ways to save a few bucks.
I ask because I used to have a good sized garden at my old house, growing enough veggies to both preserve and distribute to neighbors because I grossly underestimated the yield. While it was nice to have the neighbors love me, it was also a lot more work than I had bargained for (especially when otherwise working 40+ hours per week) and it got me thinking about community gardens and whatnot, why those might make more sense these days
