Hi everyone, yesterday i found to baby birds on the ground (one was dead and one was alive) a small bird built a nest in the space of the roof of my porch and the mom didn't build a very stable nest (she just put moss and twigs up there) the dad hit one of our windows and never came back while in the making of this nest guessing he died... but the mom had like 6-7 babies and they are super crowded up their, this one i found barely made it, ive been feeding it and its doing very good.. should i put it back up the the nest and just block the edges till they are fledglings? Any help would be good (ive fostered many wild birds but i dont know what this bird is, i normally get robins.)
