One of my hens went broody, so I got her a variety of fertilized eggs. At the same time, both the Olive egger and the Jersey Giant hatched. One of them died, and this one lived. I don't know which one it is. (There's also a chance that my brain is confused, and it could be a cuckoo Marans, but I'm pretty sure that one got cracked open in a different time. I could be confused though.) The first picture is one day old. The other ones are now, 5 weeks old.
