I hope to have a broody raise some chicks this year. I had one last year but didn't have space to let her do any hatching because the new coop was slower getting built than we'd hoped. :)
I use Deep Bedding in my enclosed coops and Deep Litter in my Open Air coop and in my runs. These require minimal attention a couple times a month between major cleanouts that take place no sooner than every 6 weeks and up to every 6 months or a year...
I think that chickens are less work than dogs because they don't have to be walked, poop-scooped, socialized, and trained. You *can* do some of these things if you want to, but you don't *have* to.
It's about the same as cats because you have to manage their litter at intervals, feed and water...
