I've seen variations on this repeated without being substantiated.
An egg is NOT a seed. If one is going to go that route (comparisons)
then the 'toxin' would be the parent animal protecting the 'seed'.
In general, the idea that an animal embryo would be toxic to consume is
silly as if these 'toxins' were poisonous to the predator they would
also likely be poisonous to the embryo itself (think of the bird
predator).
