I'm all out of pellets for now, and the tiles are starving, I have no seeds I can give them to keep them calm either. What can I give them for now?

You could give them Vegetables or some treats,nuts and millet if you have some.If you have anything bird safe you can feed them a little.

If you give them bread, that will help them get enough calories to keep going until you can get some more pellets and seeds. Bread is mostly carbohydrates, which is what seeds and pellets are mostly composed of too. Whole grain is better than white bread but use whatever you've got. Corn tortillas would work too, since corn is a grain. This is just a temporary solution not a long term diet.

Vegetables are pretty low in calories but they will help supply other nutrients. If they'll eat cooked beans (frijoles refritos, yum) that will help add calories and protein to their temporary diet.

Here's a list of foods you can feed a bird. Hopefully you'll have some in your kitchen already.

Thank you all! I feel very bad now because I was out all day yesterday and I couldn't feed them ANYTHING! They only ate what was on the bottom of the cage, so they're gonna be VERY hungry and eat whatever I give them (hopefully)

You should always have food in stock. They rely on you to feed them. Please get some bird seed as soon as possible.

They're eating bread
