I was given a bunch of fertilized eggs, one was green. I put them under a broody hen last July. They started laying yesterday, either I had the same pullet lay two days running, as there was a green one this morning, (I had an open house at school, and did not gather eggs last night) and another tonight, or I have two of my pullets laying green eggs. Three pullet eggs, a tan, and two green. I do have 3 pullets, but I didn't expect them to be daily layers right away. Life is always fun, with chickens!
