That's exactly what it looks like! What does it smell like? I'd say someone was trying to feed your chickens. If not, I've seen some weird eggs when they first start laying. It could be one of those as well.
Thanks all! The lash egg theory sounds pretty legit. I adopted my ladies from a family that couldn't keep them anymore because the neighbors were complaining and I'm a sucker for rescues! They also didn't seem like very educated people and couldn't tell me the exact age or breed of the girls. They are very friendly and healthy so I was happy to give them a new home. We've had them for about a month now and I'm starting to get the hang of their routines. From what I can tell, I have 2 cinnamon queen sex links, a new hampshire red, and a blue andalusian. Most of the time, I get 2 brown eggs every day, some days I get one. I'm pretty sure they are from the sexlinks because I have found their feathers on the eggs. The little grey hen lays little white eggs only on hot days, so my bet on the old hen is the new hampshire. Is there any way to tell age? I'm a first time chicken owner, so I was pretty alarmed when I found this. Any other advice from seasoned chicken owners is most welcomed!
