Hi Pepe! Good...I'm glad you're going to do some experimenting. I looked all over on the net for pictures of parasite 'eggs' but they're all oval or round...not 'bean' shaped. The bean shape seems to indicate seed, doesn't it?
If they are poppyseeds (which look round from far away, but aren't up close!)...then it's strange that they all came out at once! But then we are strange creatures...ha. (Clary's came out all at once too - looked like coffee grounds in the toilet - just them and the stones)
Look forward to hearing your poppyseed experiment!
