Do doves always hatch 2 chicks, one of each gender?

[Chickengirl1223]

I have always been told that doves and pigeons hatch 2 chicks, one a male and the other a female.
I want yo know if this really does happen and if so, how does this occur.
I am just trying to get a better understanding of sex change in birds, which I am doing a science project on.
Can anyone tell me if doves really hatch in a "pigeon pair"?
Thanks

They can hatch a male and female, or 2 females, or 2 males. You don't really know what the sexes will be until after they hatch and grow up a bit. But it's definitely not always a "pair".

That happens only in a perfect world not in real life.

Is @laughingdog OK?
Not seen a post or comment from him in ages.

Two young because they only lay/brood 2 eggs at a time. @Old_Strain_Lover nailed the gender possibilities.

So far my chicks have always been one of each but I guess anything is possible.

it's just 50 50 luck what each egg will be.

It's not true it's always one of each sex.

It's not true it's always one of each sex.

Keep thinking that as long as it works for you.

I think it's better to say, they lay 2 eggs before sitting on the eggs seriously for the hatching process.

Whether 2 eggs will hatch, depends on the fertility and other external conditions, including skill of the birds (though that gets better as the bird gets more experience).

And then as far as sex, it's not determined by the parents or by some kind of hatching process. With a 50% chance on 2 eggs, it is very possible to randomly get the combination of babies that old_strain_lover mentioned.
