Texas Indigo Laying

A friend's Texas Indigo laid eggs today, I believe there was 21, all of them were somewhat yellow, we assumed that it was the sphagnum not being fully washed. The female, who usually leaves the nesting box stayed this year, wrapped around the eggs, leaving a few not shaped quite right, a few of the eggs were sticking together, which is what some breeders use as a rule of thumb for fertility, I am still holding out hope for him that they are fertile, and do hatch, I will have a photo up in the next few hours. I was hoping anyone can drop some reassuring stories about their indigos, or some good tips on what to look for.
