i went into the coop this morn and i looked in the corner, and saw a soft shell egg! it was thick enough to withstand poking but it squished. I threw it into the compost pile (which is getting quite big!) so it could rot in the spring. i my mom told me that we will get oyster stell sext time we buy feed, and my feed is running a bit low, so i guess it's time for the good ol calcium!
