I'm having a problem with my copper black maran eggs not hatching. I run a mixed flock and incubate a few clutches of barnyard mixes every year. I've been doing this for about 4 years now.
I run both a cabinet incubator and a table top. Both are at 100F at 50% humidity, bumping to about 65% at lockdown.
At the beginning of the year, I had a bantam cochin over my hens, and my hatch rates were about 60% across the board for all breeds. Not great, but about average for me.
I then put an Amercauna roo over my hens, and my hatch rate has plummeted, especially with my copper black maran. I had not hatched a single egg from her in my last two clutches. I performed an eggtopsy, and all chicks were perfectly formed and ready to hatch, but were dead without signs of internal pipping.
To see if they were maybe drowning (without an internal pip, this seems unlikely, but idk) I ran a dry hatch and still had no copper black cross babies.
Interestingly enough, my full blooded amercauna chicks hatched out at a 75% rate.
The only thing that has changed is the new rooster covering the hens. What are the chances of a genetic incompatibility? Would that even lead to fully formed DOA chicks??
