Egg bound?

[babyknees]

There was a thread not to long ago of a BP that died egg bound but her clutch seems to be doing well last I read. They dissected the eggs out.
I would die if this happened to me.
I couldn't imagine losing one of my baby's.

I saw that thread and that was what got me worrying and thinking about it all.

Could be a twisted oviduct that causes it or the eggs can actually be attached to the oviduct lining. I think size is a lesser factor that would cause it, as it seems that good size females can just as easily become egg bound as smaller ones.

I would have no plans of breeding an under sized female but does that mean that there is nothing that can be done to avoid it? Are there studies or research about this?
