You might see something, you might not. It depends on the egg, your candling apparatus, and your eyes. lol I usually wait until days 4-5 to really start candling.
How long were the temps that high? 105 isn't really terrible unless it's that way for an extended period of time. In the past, I have had spikes past 110 and the chicks still survived. I wouldn't give up on them yet, and honestly I would be surprised if they are all dead. A hen's baseline...
