At the moment I am trying to candle a Black Croad Lachen egg at day 17 and a shop bought Royal Leghorn blue shelled egg at day 6 . I am finding it so tricky with a proper candling torch? Any other suggestions? My croad has a detached aircell which has not changed shape at all since day 1 . I am now at day 17 and have been putting the egg pointy side down. I can see the chick has developped but cannot see clear movement at the moment .
