I candled my chicken eggs this morning (day 7), and realized that one of them is fairly malformed. I do not remember it being this way when I put it in (not impossible, but I don't remember it being this way). So far, development looks great, but I am concerned with viability going forward. I just read that malformed eggs are not good for hatching, but I also don't want to toss an egg that so far seems to be doing fine. Any experience with--or knowledge of--this situation?
