I just realized you are in Portland too! I had some Welsummer and Maran eggs last Summer and after a couple weeks I could finally tell which were clear because they did glow in a way the developing did not... not that you can see any of the development, but I hope all yours are growing!
Thanks! That makes me feel a little better. I've had some tough luck with shipped eggs lately (I guess that's pretty common, though). I always hope for 50% at best. But now I am more hopeful that my Black Copper Maran eggs will surprise me.
I'm technically in Vancouver, WA but attend college in Portland and travel through there frequently. I love Oregon.
I'll have to look out for that particular glow the next time I candle!
