OK I'm jumping on the May Hatch-a-Long Train!
I put 24 shipped Canadian Bresse eggs in my incubator 12 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 candled on day 3 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 Bresse 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!
Captains Log: Day 6
2 Non fertile Bresse
2 Blood Ring Bresse
2 Questionable Bresse
18 with air cells and veining Bress
11 with air cells and veining Bantam Wyandotte GL
Total
29 viable to hatch 2 maybeys
Captains Log: Day 10
17 viable Bresse 1 with air cell on side (will have to research)
3 duds: 1 non-fertile 2 Blood Ring
11 viable Bantam Wyandotte GL
Total 28 potential Chicks
AND The Scotch Tape Baby is still viable! Cool Huh!
I am tempted to candle again tonight but will be patient and stick to my schedule for day 15.
For shipped eggs I found this post
extremely helpful
