Just an observation... no offense intended.

That tub looks like it is in aweful condition. It looks very dirty, and the water bowl looks near empty with feces in it. If that snake just laid eggs, then it has probably been at least a month or two since it last pooped. So is it safe to assume then that it has not had fresh water in a long time?

I have read before that a BP will not lay the eggs until the conditions are right, and they feel secure... with proper temps and humidity. This is a reach I know... but maybe it was so disatisfied with its living conditions that it tried to hold on to the eggs so long that it ended up messing them up.
