onthespot, I think you may be on to something wondering what role the inner parts of the egg have. And poltroon, I hadn't thought about how much more damaging driving vs. flying would be on shipped eggs. I bet that has alot to do with this because the only other hatch I've had that was close to this bad (2 of 10 eggs hatched) came from Texas.
And, onthespot, I have had so many shipped eggs that hatch between 90-100% for me. Only two were bad (bantam faverolles from texas and true araucanas from the southwest). This was my first and only zero % hatch. As far as staggering my hatches, I incubate my eggs in a
brinsea and hatch in a styrofoam still air hovabator. So, my mille fleur d'uccle eggs that were ready to hatch went into the hovabator days 18-21 while the rest of the eggs stayed in the
brinsea. Then my buckeye eggs and ameraucana eggs went into the hovabator on their days 18-21. I've always been worried that the humidity spike from hatching eggs would affect still incubating eggs. So, I use the hovabator as my "lockdown and hatcher".
This was a very informative thread to read and clearly demonstrated why shipping eggs is detrimental to the eggs and why sometimes the hatch rates are not very good. I would like to commend everyone, especially Jim and Titania, for their very civil and honest interest in trying to discover the root cause.
thanks. Jim seems honest and like he treats his chickens right which is why I ordered eggs from him!
