Here is another fun blog post about candling.
Eden and I built a candling box and it worked okay, but we had way better results with Brandon's LED Maglite. I cupped my hands over the light in a dark room and left a small space for light to escape from my hands. I set the egg there and voila! It worked like a charm!
I did a couple of eggs from each incubator yesterday and I could make out very distinct (and wiggling) embryo and blood vessels!
|Easter Egger blue egg with embryo and blood vessels visible. Day 3.|
Of 52 eggs, 25 had clearly visible, viable embryos.
12 had good looking air sacs and looked like they would probably end up being viable, but I either couldn't see through the dark shells (9 of these were from the Marans with the chocolate eggs) or the embryo was hiding.
|Air space is visible at the bottom of the pic.|
11 looked completely clear (I kept them in the incubator for now and will recheck them in a couple of days).
|Looks clear to me.|
1 had 2 cracks in the egg that were not visible until I candled it. It looked clear and I removed this one from the incubator.
2 had what I considered to be very distinct blood rings (based on photos I found on the internet- this is my first actual experience with this) and I saw no embryo or vasculature. I also removed these 2 from the incubator.
I wanted to reconcile what I was seeing by candling with what was actually in the egg so I opened the 3 "bad eggs". I tried to get photos, but I couldn't get the camera to focus at all on what I was seeing.
The egg with the cracks that looked clear to me had a nice little embryo and lots of good blood vessels. If the cracks hadn't been there, it would have likely been a lovely little chicken!
The 2 with the "blood rings" made me a little bit sad. Both of them, when opened, looked healthy and viable! The blood rings were actually a circle of blood vessels and in the center of it was heavy vasculature and an embryo. All I could see when I candled them was the ring. It was a dark, heavy line of red and no other blood vessels were visible. I will not be so quick to toss eggs with blood rings next time!
