For your location, current conditions, and minimal effort, I would say mulch would be a solid addition.
Bags of leaves from your neighborhood, wood chips from the local facility, yard waste, grass clippings, kitchen scraps, compost, whatever; just pile it on. If you want, mix some seeds into all that mulch, especially seeds of nitrogen-fixing support species, seeds of fast-carbon-pathway plants -- plants that produce a lot of mulch themselves, as well as seeds of plants that will grow to feed the animals.
The mulch will begin to create the micro-environments that will make germination possible, even if rain is sparse right now. It will protect the soil, it will create dew pockets, and the decomposition process will release water at the same time.
(I would even drop some logs throughout, to create more varied micro-environments and home for fungal diversity.)
You want the mulch deep and varied. Six inches to start with, and many different components should make up that mulch, not just one (i.e., not just wood chips, but, rather all of the above).
No digging necessary. Let nature's myriad critters do that for you. The mulch gives those creatures a home, gives them protection, invites them in, and they go to work. And the chickens will love it, because chickens eat a whole lot more than just grass.
With the mulch protection, the area will also begin to seed itself. There will be seeds in the mulch already. And the mulch will give seeds from the wind and seeds from the birds a place to get caught. So, even if you didn't add any seeds, you would start to see growth of all kinds of pioneering plants; lots of rabbit food.
Once the mulch begins to break down, add some more now and again, until the system can support itself (assuming you added sufficient support species; otherwise you'll fill that roll by adding mulch every couple of months). You get abundant diversity with minimal effort, and you lighten the local waste stream at the same time.
