I am jealous that you all know when yours are due to hatch!  I have 14 eggs under my ameracauna, and I didnt know about them until sunday, so I have no idea when they are due!  I did candle them and they are all mostly dark (except the air pocket) and a few I could see a small amount of veins.  They should be due soon, I just wish that I knew!  I also discovered sunday that my turkey hen is sitting on 12 eggs also!  I candled them sunday night and didnt see any growth, so who knows.  I have never tried to hatch any of her eggs, and I have never seen the to try to breed her.
congrats on everybodys new babies!
