Random Thought

It could be the immense amount of work related stress talking, but I had a strange and yet truthful thought this morning: How can pro-lifers, that believe life begins at conception, bring themselves to eat eggs?  Eggs are just that, chicken conception, chickens that have ceased to be.  Why is is wrong to get rid of a human woman's eggs after a successful in-vitro operation, but it's okay to eat what once was potential chicken spawn?  Is it because chicken eggs are used to sustain human life?  Because they serve a purpose and are not just going to waste?  Would pro-lifers feel better about it if we turned those unused human eggs into a food source?  I doubt it.
