Thank you for taking care of them. It's good they are a bit bigger as it's easier than the new ones.

For tonight you can feed them a few moistened/completely soft dog kibbles (or cat if you don't have dog). This is not so great for them but will do in a pinch until you can get to an open pet store. You'll want to get some baby bird formula, such as Kaytee Exact or similar (they will help you at the pet store). It is a dry powder which you mix with warm water to a consistency around melted ice cream. The parents let the baby put its beak into their beak, so it's rather easy to mimic the way they feed. An easy way to feed them is:

Please keep them warm, use a heating pad on low with a towel if you have one, or even an old sock full of uncooked rice can be microwaved every few hours.
Please keyword search "hand feeding" and "babies" and "baby" so that you can read some of the other threads about hand feeding, which just about cover all the tiny details. A few things. . .When you mix the formula, let it sit as it will thicken, then add more water. You can add 1/4 tspn (organic if possible) plain yogurt to the mix once a day to help with digesting. Feed until crop is full, but not stretched too full, somewhat like an inflated balloon but not like one that's about to pop.
I don't know that we have any members in your area but if so they will say so hopefully. If you can get some pictures that would be great and we can determine their age. They are usually weaned onto seed around three-four weeks (sometimes later when hand raised) so it won't be
too long of a project for ya.

Prepare to fall in love with them, they're cute little things when they're at that "ugly duckling" stage. Good luck and please feel free to ask any questions you think of.
