Ok, so I candled the eggs tonight! But the results were not as conclusive as I had hoped...
First, the good news...
Out of 18 Easter Egger eggs, 17 were DEFINITELY alive! Also the two eggs from our Blue Copper Maran for Olive Eggers were both
alive! I was amazed that we could actually see into the Marans eggs, just using a small (bright) flashlight with the foil tube on the end. Yay!!! These are all just under 1 yr old pullets btw and the EE roo is also only 1 yr old.
On the other hand, we had a TERRIBLE time seeing into the 16 Delaware Eggs! They are the darkest brown of our mixed laying flock, and rather porous. We managed to see faint veining in 3 or 4, but honestly a lot of the others almost looked like clears, or MAYBE could have had a slightly darker blob near the top, it was so hard to tell!
I would be very surprised if they ended up being mostly infertile, our Delaware Rooster is just under 2 yrs old, but he IS in with 30 hens. I tried to check the eggs ahead of time from each of the 4 Delaware hens for fertility, and THOUGHT they were good, but now I am not sure. I am surprised that we had so much trouble with these but could see pretty clearly into the Marans eggs! Oh well, I left them in for now and we will see in a week or so.
I also had 10 Delaware mixes from our flock, and again, most of them were inconclusive, and possibly clears. Only one definite good one, and possibly two from our one BO who lays a surprisingly dark brown speckled egg.
So to recap...
Easter Eggers - 17 good, 1 possibly clear
Marans/EE - 2 good
Delawares - 4 good, 12 inconclusive
Delaware Crosses - 1 good, 9 inconclusive
Total out of 46 eggs - 24 good, 22 inconclusive
