My broody hen started a clutch (eggs collected from the various hens) on 8/25. I expected chicks on 9/15, but when I got home from a trip on 9/14, two had hatched already! Now I have 5 chicks, and 5 unhatched eggs - by my count, it is day 23. The chicks have food and water, and seem to be fine. So - how long should I wait before removing the unhatched eggs as "duds"? Of course I did nothing so sensible as marking eggs - I don't have a candler, just held up a few of the eggs to a bright light (with my hand to block off an area). I would hate to kill any by opening prematurely. Thanks for any and all advice.
