I would never trust Stella or the other two cats near baby chicks but Stella for one walks among the chickens, even the young ones. Once chicks are a few weeks old, I trust them much better.Our Humane Society has a separate adoption program for barn/"working" cats. I agree with the suggestion to reach out to any local Humane Society/animal rescues in your area.
I no longer have outdoor/barn cats (for various reasons), but there is a local stray who patrols my yard and keeps an eye on the rats.
One caution is that a barn cat might go after chicks, so take care if you have little ones running around.
