What a great thread! I'm glad so many people are going with nature's original egg hatching method.
Maybe this was asked before but search hasn't turn up anything. I don't know whether my eggs are still alive.
We've had our flock about 3 months. I bought them from a friend at work who wanted out of the "backyard chicken thing." About a month ago I put golf balls in the nest boxes (3 boxes for 9 hens and a few pullets), which triggered a broody hen so I decided to give her eggs to sit on. There are several roosters so we have no shortage of fertile eggs. And we are raising them for meat as well as eggs so we want to have a self-populating flock. (This same flock hatched a brood last summer in a brush pile at their former home--nobody knew it was going on until 20 fuzzy little chicks came out. So clearly at least one hen has the necessary instincts.)
I put 7 eggs under "Broody" on December 18. According to the perfect 21 day conditions that means they should have hatched on Jan 8. Since broody hens aren't a perfect incubator I estimated they'd probably hatch anytime this week. I work during the day and collect eggs in the evening, and on the evening of Jan 2 Broody was no longer on the eggs and they were cool. For all I know, maybe nobody sat on them all day. In mild panic I grabbed the nearest hen and put her on the eggs and she seemed to settle in there for the night. The next day I had to do the same thing. DH and I wondered if we should throw out the eggs since Broody had abandoned them for two days. We hadn't made up our minds and on the next evening, there was a new hen sitting on them, happy as a clam. "Broody 2" and has been sitting on it every day. We decided that since this is a new experiment for us, to let her brood and see what happens.
Additionally, there are now 25-30 eggs. I allowed the other hens to lay into the brood if they felt like it because I know that last year's chicks had to be laid over several days (there were only 3 laying hens last summer) so nature doesn't seem to mind if they're a little different in age.
Do you think the embryos died when "Broody 1" abandoned them? Or do you think growth was just slowed down? I'm starting to think they're dead. I am hesitant to candle them because the hen doesn't like me messing about and from what I've read you're supposed to leave eggs alone in the last several days.
