Ok the short version! I've bought an incubator,put 4 Pekin eggs in, I'm also leaving eggs in the nest to see what happens! I'm on day 6,tried candling, the air sacs seem to be going the right way but can only see a dark area in two of the eggs, nothing like the detail on the charts. Wondering if my torch isn't strong enough to pick anything up? It's just a regular headlamp on the bottom of a toilet roll! Will wait a good few days, don't want to chuck out a duckling!
