Pigeon fertility

[Hillybean]

Hello,
I was wondering is there anyway to make Beautiful (hen) and Whiteflight (cock) more fertile. Beautiful is a Mookee pigeon and Whiteflight is a tame feral.

Beautiful is 3yrs old, but has only laid eggs for 2 years. At that she only ever lays one egg and it was not rutinely.... She has tried several times to get a mate, but never had any luck.

Whiteflight just hooked up with Beautiful this summer. Whiteflight is about 1 yr old. They mated once and she laid one egg. They both did so good at taking turns. After 20 days, they gave up.....it was a no go.

They allowed me to check the egg, 1 week after it was laid. I didn't see anything, but allowed them to keep it.

I'm not saying, that I want them to have a ton of babies because I don't. I just want the option to be there for them....

3 real Questions:
Both were handraised....would they know by instinct on how to feed a baby?

Is the first set with an actually pair always fertile, or is this something really to not worry about? I guess, I'm not sure on how to ask the question.

Could her only being able to lay one egg be the problem???

I offer plenty of calcium, I think.....fresh dark greens, hi cal grit, a special light that gives off the same thing the sun is suppose to. I learned about then light from when I saved a few starlings...figured it couldn't hurt the pigeons. They also sun bath on heated sand stone (heats naturally from the sun-near a window). They also have vitemins...

Any imput on this would be awsome...
The reason, I'm asking the question now, is because they are actively mating again . I'm just curiuous..... for any input I guess. I do have fake eggs....
