I was out locking down my birds and found an egg in the run. The birds have been out foraging but I leave the run open so they can come and go. There was an egg in the run. Small egg. Smaller than the Silkie eggs I have in the incubator. I will try to get a picture later. All of my adult hens are over a year old with one that is 2 years old. The oldest pullet I have is almost 11 weeks old. Am I safe to assume that it had to be one of the adults? I have 5 eggs in the house and one out in the nest box that I forgot to bring in and 6 a day is what I have been gathering. If my young pullets are not old enough to lay and I have been getting 6 eggs a day, 2 of them are duck eggs, how do I figure out who dropped this tiny thing? I have one black hen, 3 EE' hens 2 white, one shades of brown/grey 1 Salmon Favorolle hen 1 Cornish cross hen 1 Red Production I don't think it belonged to my black hen because when she went into the run, I was herding them to the chicken door, she stopped to look at it and peck at it. I realized what she had and ran to get it before she broke or cracked it.
