But they're great for redundancy (more & varied egg supply reduces the impact of supply chain shocks), to get the best quality eggs you can, and because it's just fun & rewarding.
The argument against backyard chickens would be health considerations i'd say, not cost. Curious.
My parents have a coup on their hobby farm which my dad built on the weekends. It looks great and the eggs taste even better. That said, they were never under the impression this was a way to _save_ money, the math just doesn't make any sense.
So realistically the difference is that I get fresh eggs every day, I never run out, and they are fun.
They lay their eggs in basically anything. Mine sit in a Aldi crate on it's side.
$600 on the largest coop Tractor Supply sold. It is just barely big enough for all the chickens but it does work.
The rest on reinforcement hardware since I have hawks and foxes all over my property. Metal mesh and wood to reinforce all around the coop. Also things like sand to fill the bottom of the coop, anchors to keep it down, etc.
Over time I spent a bit more to replace some bullshit hardware of the coop.
I could have saved some by building the coop from scratch but also this one has a nice design that I wouldn’t have come up with on my own without seeing how the chickens actually behave.
That said - we have had a lot more coop expenses than expected, because our neighbors wanted to be jerks about it and I wanted to keep the peace. So realistically the "savings" we would have had in egg costs have likely been eaten up or significantly reduced by having to rebuild / move our coop.

For the opossums, it's a stand off, the rooster just acts tough and makes a lot of noise so you can hopefully show up and scare it off. Weasels are annoying as they'll destroy eggs. Fox are particularly problematic though. They'll easily kill a rooster and are very quiet and conniving.
I think this is the catalyst I need to get started on a coop. If anyone has any plans or pointers for a coop, or raising chickens in the SW, would be much appreciated.
All that to say: the minimum threshold for starting backyard chicken keeping is very low. I’d recommend jumping in as cheap as possible and upgrading later if you find you enjoy it.
