I am in the midst of candling as I type. I am seeing much better rates with my own eggs. Less time from chicken to incubator, the better it gets. My first batch sat for at least a week before going in the incubator. Out of the thirty six eggs I set, only four are kicking around at my feet. I would say more than half were not fertile, had a few embryo deaths, seven of the fifteen I put into lockdown hatched or pipped, one did not make it out of the shell, and two chicks died at a few days old. That was my first hatch! Just wretched, but now my own hens are laying and I have candled a good bit of them.
Here's how it's looking. March 6th, 7th, and 9th I set forty-two eggs. As of today's candling there are nine that I tossed that were either not fertile, and a couple with obvious blood rings. Now that I have green and brown eggs, there are eight that I cannot even see into with two lights. But that leaves me with twenty-five that are most definitely developing up to this point. Perhaps it still will not work out in my favor, but at this point it seems to be going well. I have a whole other incubator full of eggs that need candling, but hopefully that one bears good news. My first eggs should start on the twenty-third, and I have a staggered hatch from then on. We'll see how it goes! I have a whole week off to admire the darlings, so hopefully I will get some darlings to admire. The first eggs due to hatch are purebreds, but all of my eggs have little mutts cultivating inside them, so it will be a very interesting event.
