I put 24 shipped Canadian Bresse eggs in my incubator 2 days ago. They traveled all the way from British Columbia to me in NE Quebec. In the US that would be the equivalent of LA California to Bangor Maine lol. I should have let them set a full 24 hrs before putting them in my incubator but they were a week later than I had wished and have other breeds in line for the next 3 month following. So They only sat about 10 hours before they went in. I have them point down with no auto tilting at the moment. I plan on candling tomorrow night to determine the air cells. I also added some of my own bantam Wyandotte lace wings eggs as long as I was running the machine. One arrived with a tiny spider crack in it. I saw someone successfully hatch an egg on YouTube is similar shape once by just putting a piece of scotch tape on it. Why not? I haven't got anything to loose!
