I have a question about hatching egg viability. We did a few hatching eggs presales this spring. Our Buff Orpingtons did not cooperate and started laying late. Anyway we shipped some eggs to a lady at her Post Office Box in Sumas, Washington. (Sumas is on the Canadian border). Mailed the box Priority Mail Flat Rate on 5/17/11. About two weeks ago i received an email from the USPS stating the item had not been picked up and after the 15 days, it was being returned to me. tried calling the buyer. tried calling the PO. No answer from either. I did a Yahoo search for her phone. It was a British Colombia number. CANADA! OOps, no shipping papers for there. The eggs arrived today at our house. The eggs have been in a well packed carton for 6 (six) weeks. Should I open them, candle them and set any that are not spoiled. Or just toss the box before it explodes? ETA: One egg was broken. Smelled a bit bad. The rest seem alright. None cloudy or dark. Am considering setting them.
