We have had a couple of these in the past. Never a blue one though. Almost missed it in the nest. All of our EE's are from 6 yrs old to 2 1/2 yrs old. Silly chickens!
Is the shell hard? Hard to tell from the pic. Hard to say what I would do. I think jus out of curiosity I would wait a few days and candle it. I don't really know if it would survive even if it candle well, but I would give it a chance. Could be the most awesome chicken you ever had. Please keep us posted! Good luck.
