I just candled, day 14 on buff orp shipped eggs. i discarded two as they candled clear/yolk looking and one of those had an odor. I cracked them open (outside) and was thrilled to just see yolks (terrified I'd see a chick here's my question. what I could see on the ones I kept was mostly dark, nice air cell at top. I had seen movement on these eggs on day 7 (so cool). three of the eggs had their air cells extending down along the side. Is that normal? the rest had air cells in a neat circle at the big end. I had this crazy thought, maybe because they were shipped in the heat and collected over a period of a few days, could some be farther along than others? Any help would be appreciated!
