I have an incubator that we mostly loan out to my kids' schools. The last couple of hatches haven't worked out, which I assumed was user error, but decided to try some eggs at home to make sure the incubator is functioning properly. Tried some eggs myself, still nothing. Decided that maybe our old rooster just isn't fertile anymore. To test this out, I got some eggs from a neighbor lady who has chickens and roosters to see if hers would develop in my incubator.
This is where things get odd..
Neighbor lady brought 7 eggs she insisted were 'from this morning' (yesterday). I didn't get around to doing anything with them for about 18 hours. Some were filthy. Candled them and some were cracked. Just not good quality eggs. Candled the last one, and... ahh! Definitely a chick in this egg. And it appeared to be moving. Based on the size, air pocket, etc, I would estimate about 16 days. Normal looking, strong veining, nothing notable. Not knowing what to do, I put it in the incubator. But, this is after it sat on my counter all day and also took a ride in the car. I can't imagine it's possibly alive? All I can think is that it appears to be moving because it is an old, dead egg and has bacteria or something in there. Is there a way to test this out?
I don't want to give up on the little guy if there is really a chance he's living, but given the circumstances it seems impossible. He would have to be some kind of magical zombie chick. Would would be neat I guess, but not probable.
I should add, this is definitely not *just* like a huge nasty ball of infection. It is assuredly chicken shaped with matching air space size and visible veins. Of course that does not rule out well-developed, bacteria-infested dead chick.
What should I do?
