Hey, guess what! My pigeons payed eggs as well as staying faithful to the chicken egg! One I found cracked in the floor though

I think it was later outside the nest and it fell off. Chicken egg is doing good, if not a little behind. A friend also gave me a sparrow egg to see if they would hatch that, so that’s under them too! So now there is three eggs, all of different species in a pigeon nest. Would the baby sparrow be able to be fed by the pigeon parents, or will I have to take it away? I’m kind of freaking out over the pigeons eggs though, I really hope that one hatches most of all
