Feral Felines Get Friendlier!

I've been feeding some (mostly) young cats for over three weeks now. They're living in our old, temporary chicken coop; it's made of straw bales with a truck cap. See them here. They'll now come running when I call at feeding time! They mostly still keep a wide berth, though. Two, of eight I see regularly, are a little older and they will come right up to me. The younger ones will do circles around me to get to the food. They spook and run off if I so much as sneeze. But, they're getting a bit more comfortable; three of the little ones have been creeping up to sniff at my feet. I put food out in a couple of piles and then sit about three or four feet away. Some have been bold enough to come up within a foot of me to eat from the food container I bring. They are all beautiful little cats, one is a gorgeous tan shade with white feet, two are seemingly twins of orange and white stripes, one is a little grey with a short tail. One of the little ones is a brown and black striped cat with a fluffy mane - so cute! Farmer Man keeps asking what I'm going to do and I can't fully answer. I'd love to tame them all and find them loving homes. Is that possible? I don't know. I hope to, at least, help keep them alive and comfortable through our frigid winter. I'll keep you updated!
