These are fledgling Mourning Doves. My best advice is to put them back where you found them and see if the parents continue feeding them, and if they don't, take them to a wildlife rehabilitator near you. It's really difficult (and illegal!) to care for these birds by yourself.
ETA: Here are some helpful links for you:
Also, welcome to WhatBird!
I agree. Doves are especially hard to care for because the parents secret a "milk" from the lining of their gizzards which is very difficult to synthesize.
Agree. However, it's a myth that the parents won't take them back if you touch them. They'll take them back just fine after they're handled.
Most birds have a very weak sense of smell and would have no clue that a human has handled the chicks.
You should read my post in this thread (http://www.whatbird....__fromsearch__1
) for advice on what to do when you find a "baby" bird.
