Baby birds by my front door - are they being fed?

Leave the birds alone..they are being cared for. Birds sleep at night..when they are very young, the parent(s) will sleep in the nest with the baby birds..it is important not to scare them off of the nest at night as they have poor night vision and may not find their way back to the nest. Once the chicks are older and more feathered, the parent will no longer sleep with them but will sleep elsewhere and return in the day to feed and care for them. The eggs NEED to be incubated to hatch..so yes, they are being cared for. If they were not being fed they would be dead.
