We thought that our new girls had stopped laying for the winter, but it turns out that they just decided to start laying in a secluded corner near the shed. My son found the cache on one of his rambles around the yard and we brought all the eggs (18!) inside and I rinsed the dirt off of them. Since the temperatures outside have been below 50 at night, and probably no higher than 55 during the day, I figured they should be fine. We have two new hens, and they aren't daily layers, but are pretty reliable. I figured that the 18 eggs were laid over the course of 2 weeks or less. Today I cracked two to make brownies and the shells had dark spots on the *inside* of them. I felt uneasy about using them; one of them looked perfectly normal on the inside, but the other one's yolk broke apart really quickly once I cracked it. I did the egg test and none of the eggs floated in cold water -- they all sank to the bottom of a bowl. However, a couple of them released a few tiny air bubbles. I'm wondering if laying in little depression in the wet Seattle weather did damage to some of the eggs -- or if I did them damage when I washed them off (I know that the eggshell has natural oils that keep it non-porous - right? - and either the rain while they were outside or my washing probably didn't help that). So -- given all that babble, what do you peeps think? Are the eggs safe to use?
