If the mother doesn't come back for the baby then you should bury it or if you're really careless then you would leave it for the cats.
If the mother does come back then leave her and the dead baby alone
The jays nest is made of coarsely built with sticks, lined with grass and well concealed in a crotch or forked branch of a tree.
The Blue Jay usually builds a nest from twigs, bark, small roots, feathers, scraps of paper, or cloth, and mud. They prefer to build in an evergreen, but the Blue Jay is flexible when it comes to the nest. They will make do with just about any bushy tree, or large bush that is available, even resorting to the old country style mail boxes, or using another midsized birds nest. The Blue Jay is listed by the IUCN Red List as "least concern". For more details, please see sites listed below.
One of the only birds that lay blue eggs are Blue Jays, they do not usually lay them on the ground though. There is a very good chance it fell out of a nest.
No, because your scent is on it.
Blue Jays are very territorial, so they will most likely attack anything that comes close to their nest. If a bat is small enough, they will kill it.
He dies.
Then the other parent has to take care of the nest.

I have heard that in certain species the first born of biggest chick will knock the others out so it gets all of the food. The strong lives the weak dies.

The Hornbill
Yes, but it does not build it's own nest. The female Cuckoo lays one egg in the nest of another species, like the Reed Warbler, Meadow Pippit or Dunnock, removing one of the existing eggs to keep the number in the nest the same. Each female will lay an egg in 12 to 24 host nests each year. Once it has hatched the Cuckoo chick pushes any eggs or chicks of the host parents out of the nest so that it can eat all of the food that is brought to the nest itself. Neither the natural mother or father of the Cuckoo chick plays any part in bringing the chick up. Instead, the "adoptive" parents believe the chick is theirs and feed it. By the time the Cuckoo chick leaves the nest it is massive compared to a chick of the same species as the nest builder, but the adoptive parents probably do not work any harder as instead of 5 to 10 mouths to feed there is just the Cuckoo chick shouting to be fed.
Blue jays nest in cool climates. Places like England
A cuckoo does not make a nest, a cuckoo will lay an egg in another birds nest, the other bird will then care for the egg and chick as if it was it's own.
