I had some young chickens (just over 4 months old) that I didn't expect to start laying. I had them in a pen with no boxes. Well I started finding eggs on the cold wet ground around Dec. 16th, and didn't get an egg box in there until the 21st. So what did I do with all the muddy eggs that weren't "food grade"? I decided to try to hatch them of course! Surprisingly, out of the 11, ten of them developed eyes and veins. Then one of them quit on me and melted away around day 6-7. However, 9 are still going strong at day 13. However, since the ladies were young, the eggs are very small and when I candled them today the smallest eggs are already completely filled. Will I have problems with the hatch since the shells are so small?
