Great egg experiment update

I think the great egg experient may be a flop. The temp here have been unsteady to say the least and have made for some serious temp spikes and dips that I think might have killed my eggs. The neighbor kid swore he heard one of the eggs cheep today though and I have thought I have heard something the last few days too, so hopefully I will get SOMETHING. My broody hen got off her eggs long enough for me to candle a few a couple of days ago so I have high hopes she will be able to hatch hers. They looked right on track and I even got to see a little foot wiggling around in one egg.
I will post pics of what I do get and if anyone is interested, I will crack and post pics of the development of the eggs that didn't make it.
