For a week or so now I have been finding about 1 egg a day with a hole pecked in it but not eaten. It's been confusing me because when I had a problem with the chickens eating eggs when they first started laying, they were eating the whole things, not just pecking a hole in them. Yesterday I found a very small egg, about maybe an inch diameter. I thought it was a freak small egg, so I decided to fry it up next to a normal size egg and take a picture. Well, when I cracked it open, there was a little embryo inside.(gross!!) Obviously, it was not a chicken egg, because there are no roosters around. I think it may be one of those birds that lays its eggs in another bird's nest and breaks it's eggs. I have seen a smaller brown bird or two fly out of the coop a couple times. Anyone had this problem?
