collapsing eggs mean one of two things. The eggs are infertile (since you have a male and two females, unless there is something wrong with his 'plumbing' not too likely, unless the females are very young (under 15 months of age) or too old to breed (over 6 years old).
The second reason is the incubation material is too dry. The incubation container should have a ratio of one part vermiculate to one part water by WEIGHT. More water should be added around the eggs if the vermiculate starts to look dry or the eggs start to dimple or collapse. Add water around the eggs, not ontop of them.
I suggest adding more water to your mix and the eggs should fill back up in a short period (couple hours anyway) and should incubate fine. If they fail to fill out at all or go moldy, then most likely the eggs are either too far gone to recover or were infertile.
