I finally put together a coffee can candler, and with great trepidation took one egg out of the incubator to check it. Well, guess what: these are olive egger eggs (from Wynette) and I can't see a DARNED thing through those shells!
Which is pretty much a relief because I didn't want to see anything not positive. Not seeing any light through those shells, in other words seeing NOTHING is better than seeing something not positive. For my first attempt at incubator hatching, anyway....
Before I checked that incubated egg, I tried a white egg from my fridge (the Lakenvelder sisters lay white eggs), and while there was nothing to see, I could see through the shell enough to know my home made candler should work.
But not with olive egger, EE (green), Marans or Welsummer eggs.
At least I'm past the terrified first time fears of candling eggs.
6 more days to go.
