Pet Macaw laying eggs

We have two Ruby Macaws and a Scarlet Macaw. One of the Ruby Macaws (a rescue bird who was supposedly a male) has begun laying eggs around the house. She and the DNA verified Scarlet male have been messing around under the cages (which we thought was just playing) but she does not sit the eggs, she leaves them on the floor under the cage or on the sofa. We don't know if we should build a nest box inside the female's cage (all three macaws are pets in our family room) or what we should do. We also have 2 female cockatoos and an African Grey, so privacy is not possible unless we build a nest box, if that should be done in our situation.

Each parrot has a large cage, but not one in which 2 Macaws could live comfortably. They all spend upwards of 5 hours per day out of their cages. We are not sure if the eggs are viable because we don't really know what we are looking for if we attempt to candle the eggs. I have read that hybrids such as the Ruby are nearly always sterile. Would she still lay eggs if so? We don't have the time, the energy, nor the experience to feed babies, so we were thinking if the eggs are viable and we build a nest box, perhaps the parents will raise the young? Or should we just do nothing?
