Have you thought about just sectioning off part of your garage for the cats? That's how my neighbor introduces new barn cats, and they are all but feral. He puts up a barrier in his garage near a window and leaves them in there for (I think) 2 weeks, maybe longer. They don't require much.
Another idea is to look for a used dog kennel. That's what I have for my chicken run. I saw one the other day for $200!!! I paid $600 for mine years ago. You could use it for the cats until they are accustomed to their new home and then transition it to use for chickens. You just have to add hardware cloth around the bottom of the kennel for the chickens. You could put that entire coop in the run and modify the coop to hold more chickens.
Just a suggestion. But think outside the box! Many people don't lock their chickens up 24/7. There will be a risk of predation, but you can mitigate that risk by being mindful of their habitat.
My flock (17 chickens and 5 ducks) have a shed I converted into a coop, a covered run, plus a foraging yard surrounded by electric netting and covered with aviary netting. Other people use hoop coops (my next project - easy, inexpensive, and effective) or custom built from scratch. There are a gazillion ways to do it!
