The kittens sound like they could be feral, since they won't let you near them. If you can trap them, you might be able to socialize them and find homes for them. The mama sounds like she's already a social cat. The one problem here is, if you just leave them and provide food and water and they aren't fixed, it'll snowball into more kittens, etc. You may want to look into rescue organizations in your area that specialize in this.

If you want to take the time, I'd trap them, get them fixed (especially mama) and try to socialize them so they can be placed. It takes alot of patience and time but it's well worth it.

How about having mama fixed and keeping her??
