.. . between ostrich and humming bird, where did the chicken come from ? 
Perhaps the chicken came from my neighbor's backyard.
Btw back to topic, yeehi, had you start the project yet or you just thought of doing it?
Well, at the moment it is still in its ¨conceptual¨ stage.

Why isn´t it possible? What would be necessary to enable it?
In very basic terms, their genetic codes are just too different. A hummingbird's sperm cell would not communicate with an ostrich egg cell in order to successfully trigger embryo development.
Sometimes species within the same genus (horse & donkey, dog & coyote) can reproduce because their DNA is similar enough...but that's just not the case with these two birds.
and to add to this, even if you manage it to put egg and sperms together (this means with ostrich and hummingbird, in a petri dish); then fertilisation won't work; if you try an artificial fertilisation (and have the means for it), then mitosis won't work, the embryo would not develop. Ostrichs have about 80 chromosomes, hummingbirds I don't know...but let's use a dove (Geopelia), it has 72 chromosomes, i.e. mitosis will fail...

it does not seem possible but miricles always happen
