So last week, one of the eggs got dropped and had hairline cracks. I'm not sure how it dropped, if it was my toddler or if it rolled out of the coop. Anyways, I was going to just throw it away but I looked up what to do on Backyard Chickens and some people have had success with putting wax on the cracks. So I did that, and candled them again today (approx day 10) and look at what I saw! The black speck moving around is a baby duckling! All 4 eggs have movement in them when I candled them. .
