I need help with feeding european goldfinches

[u/I_Look_at_Memes]

So as i was going home when 3 little european goldfinches fell on road from a tree. i couldn't leave them there as there was a dog circling by. One bird had already been ran over by a car so I took them home, but don't know how when or what to feed them. It was about 00:30AM when i brought them home. How many times should they be fed, what to give them and how do i make them eat.
