Oh hai ! Just now seeing that post... ! You can check out the link in my description to see way more than you probably want to know about me and my journey on hatching these eggs lol. Currently (7/25/12) I just put in a batch this morning. I had three rounds with trial and error, so hopefully all the knowledge I've accumulated from those times will allow me to hatch one or two. Last time, one started developing, but then died after I candled it. It was so early in incubation.. I then figured I had killed all the others by candling too much (I did it several times a day. I WAS super impatient.) because I didn't wash my hands before candling and the oils from my hands had clogged the pores bringing in oxygen. That's why the egg died after I candled it. It was the only one I hadn't candled !! So now I got 15 of the biggest eggs in the carton and have them in the incubator... I won't candle till' day 8 to be safe... It certainly has been a "journey", but this is my last round with poultry if these don't hatch . It's just too much!
Back to edit how much they cost ! If you get the "Grade A Cage Free Fertile" eggs, they're about 3 bucks a dozen. I bought 2 cartons, so I could get the biggest variety of eggs and so I could incubate the largest ones. I put 15 in. The remaining eggs can be used for eating, checking for fertility, or even incubating when the first batch is done, though hatch rates will have dramatically decreased, it's still worth a shot.
