Squirrels will pretty much nibble on whatever they find. You can try offering them firmer foods that break into pieces such as crackers initially, then then might like to chew on other things such as carrot sticks. Offer them a variety of foods so they are getting full nutrition once they are off the formula. Also check around the area you plan on releasing them and offer them whatever fruits or nuts they will have available there so they can get used to those options.
Make sure while you are caring for them you limit the amount you handle them as much as possible. It is hard early on when they need formula, but as they are eating solid foods get them outside as soon as possible in an enclosed cage where they can be safe but see the outdoors and get used to being out in the weather a little more. The bigger the area they have the better. Just slip the food and water in there and keep the interaction to a minimum. If you are planning on releasing them in your own yard leave the cage there open for a little while so they can come and go. A friend of mine has had a lot of success using this method of releasing the squirrels she's raised.

Thanks!I am the only one who ineracts with the right now and only at feeding time.
They are still on formula...but one has started to gum on my fingers a bit. Since they have no cheek teeth yet and won't for awhile I worried about the type of nibbles they could safely have!
We are currently working on a cage and nesting box setup we can move outdoors and then to the release area for them! Right now they are still pretty immoble and we are just getting ready to move them to a carrier size pen for more room!
