I just had to cull a stinker out of the bator. I put it in a ziploc bag and cracked it to see what was going on. There was black stuff all in the yolk. I'm assuming that it was some sort of bacteria. I'm praying that it didn't infect the remaining 11 eggs. Though, of those 11, I'm pretty sure three of them are not going to do anything. Two of those are the Ameracauna eggs.
I'm on day 10 now, so I'm getting a lot of darker shadows when I candle. Most of them I can still make out veins on some areas of the eggs.
I have four set aside for hatching after these are done. My Black Laced Red Wyandotte has just started laying. She's in with my Blue Copper Splash Marans rooster. Can't wait to see what kind of cute little boogers come out of that mating! Hopefully she will continue to give me an egg a day until the bator is empty. Then I'll have another 15 or so to hatch! The Sept. hatch will probably be my last of the year.
We are due the same day. I just candled mine and tossed 10 of them. Most were not fertile or just did not develop, a few had started but had a blood ring, and one looked like it was just scrambled. But the remaining 10 were looking good. 8 are Catdance Silkies and two are my home growns. I am taking a break after this batch is down.
Good luck with your remaining 11!
