Woke up to a pip this morning. 
The angle I took the picture at makes it look like the pip is further down the egg than it really is. It pipped at the lowest part of the air cell.
I've got 8 shipped silkie eggs that are 19 days old now (will be 20 days today at 4:00 PM). Two pipped now and 3 that internally pipped that I added a safety hole to just in case. Of the three eggs that aren't doing anything yet one looks close to internal pipping, one has a smaller air cell and hasn't drawn down yet (blood vessels look good though) and the last one has been alive but looking kind of iffy throughout incubation (sluggish baby with a blood vessel network that doesn't cover the whole egg).
I've got another 13 eggs from my flock will be due on the 26th as well.
I know silkies are a lot less waterproof because of their feathers. If they get wet and it's cold out I would guess that it would be easy to lose them. I've heard silkies can do well in cold climates but you have to make sure they stay dry. I used to have some hatchery silkies when I lived in the high desert in Oregon. It got into the teens and occasionally into the negatives fairly frequently during the winter and our silkies did fine (we typically didn't get deep snow there though). Now we live in Tennessee and it just doesn't get that cold here. It does rain a lot and I have talked to people who lost silkies that stayed out in the rain around here.

It may just be the owners I talked to and what they believe too. But I know they had a heated coop and wouldn't let them outside once the snow started said they were not as hardy as a regular chicken and they got sick easily so they tried to be careful to keep them healthy.
