My eggs arrived today and 11 of the 12 are intact. The one was broken just a bit on the bottom and got tossed. I tried candling and could not see much of anything except that they are super blotchy/porous. I've heard that it is important to keep the humidity higher in such cases. Does anyone know what humidity I should aim for at this point? The eggs are Delaware by the way and I've read that prolific layers can often have porous shells.
