Found a rooster in my driveway yesterday

Found a rooster in my driveway yesterday and posted on my local forum but no one claimed him. I Didn’t know what to do overnight and he had a car slumber party as some redditors told me to do. Built him a little temp home with a burn barrel with some warm leaves but we live next to the woods and I’m afraid of the predators getting him!! Called some rescues and local bird sanctuary’s but I feel like chickens don’t qualify for like anything :( taking him to the vet today and ordered some antibiotics since he has an infection on his rump.

Any ideas on what to look into long term since I don’t have anywhere suitable for him?
