Well, I washed them with 105 degree running water, wiping as gently as possible, then I did a really quick, about 2-3 second dip in
Brinsea's disinfectant solution, mixed per the label rate, also in 105 degree water, than a very quick rinse, then wiped dry.
AFTER getting the poo off, I discovered more cracks. One has a definite crack mark with spider cracks radiating from it. Two more have what I believe are fine hairline cracks.
So, I decided to send the seller a message. I stated that I was not pleased with the condition of eggs being coated in feces, and that I felt the odds of a successful hatch were slim due to probably bacterial contamination.
I am of the opinion that a seller of hatching eggs has only a few basic obligations: 1) provide the quantity and type paid for; 2) provide clean fresh eggs thought to be fertile; and 3) package them adequately and ship promptly.
I believe that this seller was grossly negligent in meeting requirement #2 above, and somewhat negligent in #3. The packing job was marginal, in my opinion. Each egg was wrapped in one single layer of small bubble wrap, and the eggs were stuffed into the box with crumpled newspaper. I've seen much better packaging jobs from other vendors.
