How tiny is the tiny kitten??
I had one once that was living under the house next to me, and it was about 4 weeks old. I managed to catch it, using a butterfly net, and brought it inside, holding him by the scruff of his neck so he wouldn't scratch me. Boy was he ticked! I put him on the sofa and removed all animals from the room. He hid under the cushions for the longest time, and hissed and spit if I moved my hand close. I ignored him, and watched some tv. Every few minutes, I scooted my hand a little closer, watching out of the corner of my eye so I didn't get scratched (no idea on diseases he might have had, plus I'm allergic to cats and swell up when I get scratched...). After about 45 minutes, I was close enough to touch (I moved SLOW lol). I placed my hand over him and held him on the couch, so he couldn't squirm away and scratch me, being very careful I didn't hurt him. After about a minute, he calmed down, so I started scratching with one finger and holding him with the rest of my hand. He started relaxing and purring! So I moved him on my lap, carefully, and continued petting him. DH thought I was nuts, but I think he just needed to learn I wasn't going to hurt him. When he was on my lap and I was scratching, I got DH to bring me food for him, and he ate it right up. He was still a little skittish for a bit, but very very quickly learned to come when I wiggled my fingers, a sign we use for all our cats to let them know that we want to give them scratches and loving.
Go slow with the kitten. You don't want to scare it off, but if you can catch it, wrap it in a towel or something so it can't scratch you (snugly cover all feet!), and scratch and love for a bit, then feed. That'll show the kitten that you equal love and food, to very important things! If you can't catch it, that's okay too. Just tame it like you would with chickens - slowly move it's food closer and closer to you, until you can reach out and scratch gently. Make sure to talk in a calm, soothing voice. You'll win this cat's heart for sure!
