Making ferals adoptable?

I recently got done fostering a pregnant cat, she successfully had her kittens and they've all been adopted out. I decided I couldn't part with mama kitty and now she's mine. Now I've taken in some feral kittens from a local rescue organization that were retrieved from a storm-ravaged mobile home park. They're not aggressive at all, but very timid, though once you're holding onto one, they tend to settle down and enjoy some attention. They're probably about 4-5 months old, and the ultimate goal is to get them adoptable.  Does anyone have some good advice for helping them out, beside just handling them as much as possible?

Exactly that, handling as much as possible.

I hate this part, but the fact is, they do feed off of one another's fears, so separating them away from each other makes things progress SOOO much faster and better.

Always remember too, the way to a cat's heart is through it's tummy (appetite)

Do you mean separating them into separate rooms? Unfortunately I don't have enough rooms to do that. I have two cats of my own, my father, who lives with me has his own cat, I have a 6-month old puppy that I adopted two months ago, and I also just took in a pregnant foster cat today. The feral kittens are in their own room, and the pregnant queen is in her own room, but the other animals pretty much have the run of the house.  I'm really hoping the ferals will be adoptable within 2-4 weeks before the kittens arrive. I have my father and a friend who can lend a hand with handling the ferals and I was considering asking a neighbor's kids if they might want to come over and visit them, but I don't know them that well, so it might seem a little weird.

Sorry I wasn't thinking. I have a cat room with lots of large cages I use for ferals, taming, nursing moms and recovering cats.

Yes, this would be very difficult for you to do!!

You can use bribes (Gerber baby food is excellent).  Just a dollop on the end of a spoon, then your finger, can bring them running.  Not too much - just a taste.

You can also use a Feliway plug-in.  It uses artificial pherenomes that help calm them.

But basically, spending time with them is the only way.  Someone can sit in the room and read out loud (the neighbor's kids might enjoy that if they won't feel comfortable handling them).

You have taken on quite a challenge.  Blessings on you!

Here is a video that chronicles the rescue of feral kittens and also their socialization.  It has some really good tips.

Some more info, I'm guessing now they're probably closer to 5 months old. They've already spent about six weeks at one of the rescuers homes, but she has so many right now that she's only been able to spend a few minutes with them a day. The black and white one always hisses at first, but as soon as you touch him, he immediately starts purring. He loves to be held and petted and would probably tame pretty fast away from his siblings. The other two always run but they can be held, but will bolt as soon as you take your hands off them.  I have them loose in a spare bedroom, there's a few furniture items in there, as well as several boxes I've set up with holes cut into them. The rescue woman I've been working with says to grab them by the scruff and force them to deal with being handled and she's been free-feeding them dry food, and them giving them canned food only when they'll submit to being petted while they're eating. I haven't managed to get them to eat when I'm handling them. I hate to have to grab them, because I'm sure it's frightening for them, but if I didn't I'd spend hours just chasing them around. I'm also thinking it might be a good idea to take away the food and only let them eat when I'm with them. How much time a day do I need to spend handling them? It would probably be ideal if I could have them in the same room with me all the time, but with my other pets it's not feasible, so I'm trying to get in there at least 3-4 times a day to pick up each one and spend 15-20 minutes holding and petting them. I haven't dealt with feral cats before, with my last foster, the kittens were born in my home and with their mother up until they were adopted out, so they were very well socialized, fearless and playful. The feral kittens are such a stark contrast, it's kind of heartbreaking that they can't just be happy kittens.
