If they have feathers and can hop, that means they are fledglings and were about to leave the nest anyway. You didn't do any harm. The babies will call for the parents, and they will care for them on the ground while they learn to fly and forage. You don't need to do anything for them.

Don't touch them!!! birds don't like the seen of humans and the mom won't really like the babes if you touch tim. They are probably just learning to fly. It's normal, you probably miss interpret the mom birds expression.

So it's by our side beside the bathroom window edge. So I just opened it for fresh air and I didn't notice there was a nest there until now.. There are 3 baby birds grown with feathers and they look ready to fly. But I don't know really. But I scared 2 baby robins and 1 stayed and it didn't look like it was going to run away. The mother was stepping on their faces and they flee... I checked the backyard and there is one robin bird in the corner and the other, I don't know where. Now the mother bird is like standing on the edge of the nest looking at where I opened the window and she looks like she's panicking.. HELP what do I do ?
