They look like they're in pretty good shape. A little soiling won't hurt anything. If it's dry, most bacteria should be dead. A light brushing is okay. If the air cells aren't detached, let them set at room temp for a few hours, then set them. My eggs arrived today, and the cells were a little wobbly, but not much... and no rollers! I'll be setting them later this evening.
I appreciate the feedback! Those look like they could've come from my boxes, but my RIR are hatchery RIR. I hope you have a good hatch! I'm unsure if I should set mine later this evening, or wait until the morning. I wanted to set them on Monday, but they got here way too quick for that.
