First of all you need to separate them.... 1 snake = 1 enclosure.

Get them set up appropriately, with the proper temp gradient and humidity, as well as the proper technology (UTH, thermometer, thermostat, hydrogometer).

Then leave them alone for a proper acclimation of one week (no handling).

Get them feeding (I would recommend 2 successful feeds) before you do any handling.

Get the eggs into an incubator... although if they have been moved and have been out of an incubator for any length of time without proper heat and humidity, it may be too late.

Not to be a hater, but BP eggs are not super hardy.

There is a good care sheet on this site, not sure where it is, as well as DIY plans for an incubator. Hopefully you can search and find them, or someone will post them.

But keep in mind, this is not a few hours project... setting up a bp properly takes time, tweaking, and planning. Setting up an incubator.... X3 on all the forementioned.
