Ringneck doves and pigeons can hybridize, though it is uncommon; so the eggs may be fertile.
It is also possible that just having the other bird in there stimulated her to lay.
I would let them incubate the eggs and see what happens.
Even if fertile the embryos may die early in their development.
Good luck.
