I usually get good eggs off ebay, unless you get a package come with an 'Xrayed' sticker on it then you may as well just throw it away
! I have some hatching as I type but not pedigrees , some meat bird crosses.
I saw once on telly an inspection of parcels with a sniffer dog, the dog was just trampling and kicking about egg poly boxes with fragile written all over them , scambed egg I thought.
