I candled all my eggs last night; the Christmas eggs and the eggs for this hatch that were put in on the 11th and I have questions.
For this thread's hatch I had a couple of blue eggs that I didn't see a vein but they showed change and I imagine there'll be veining if I candled tonight. Some eggs showed a vein or two and some eggs showed embryos with vein development! I saw veins at the end of day 2 with the Christmas hatch which totally surprised me, and some didn't show development...but did show development later on.
Do some eggs start developing before others in the same group? And that much? The oldest egg of mine for this thread is from the 26th of Nov. so it's a pretty tight hatch (for me.) I don't remember seeing this in the hatches I did this summer/fall. I'm an extreme novice at incubating so I don't have the experience and knowledge for comparison. I have forced air and no noticeable cool spots. I rotate eggs in position and level to keep everything even. And as far as I can tell I should be hitting the 95.5-100 range by what my calibrated thermometers say. I have a variety of sizes of eggs incubating, but both regular sized eggs and tiny eggs showed slightly more developed eggs AND lesser developed eggs. (I hope this makes sense...I'm beyond exhausted today...lol!)
Often blue eggs are harder to see into so the veins do not show up.
