I just set 12 Lemon Cuckoo Orps at 11:15 pm. One egg is cracked. I used wax, elmer's glue, and a little tape at the worst spot. All have damaged air cells. USPS paid no attention to the very well marked package. The box was smashed on one corner. It also has marks and dents that indicate it was banded on 2 sides, like it was probably on the corner of a loaded pallet. It was double boxed and very well packaged. It will be interesting to see how these turn out. This is my second hatching. I really think I have a handle on it this time. I have my bator set up so that I only need to open to candle. I'll be candling all on Day 10. But, I will be candling the cracked one sooner and checking it for leakage and bad smell. Good luck to all.
