I think you got a old batch of eggs. The only time i got bad eggs from shipping was when they were treated very rough. I would also candle for porous in the eggs. Sometimes when you buy eggs, the only thing they care about is money and shipping anything out. I would contact the seller and try to work out a deal. I have come to expect swap eggs not being perfect, because they are swap eggs. 
I had incubation problems during the hottest part of this year, my luck seems to be changing now that the weather is cooler.  Best of luck to you!
