I'm trying another batch of eggs from Trader Joe's. I found fertile eggs in Tucson, AZ (first time I've seen them outside CA). They only had a few cartons out but there was a guy stocking eggs at the time. I asked if they had any fresher eggs in the back and he said that he'd find me in the store if he found some. Sure enough they had some eggs that were 5 days old so I got 4 dozen for $12. I still have to fly back to Tennessee with them tomorrow and probably wait a few days until I make room in my incubator by moving eggs from my incubator into my hatcher but only after all the eggs in the hatcher now have hatched (on the 19th). Anyhow, I'll get them in as soon as I can.
It sounds like you have a very good shot at getting chicks this time!
