I am looking to buy some Russian Orloff hatching eggs, but I'm a little concerned about it. How long can the eggs be cooled down before they don't hatch? I'm worried about the ship time... are they kept warm during that time usually? I can't find anyone around here that has them, so it looks like I will need to order some. If you've hatched some shipped eggs, what was your hatch rate? Never done this before, so any advice/info helps! Thanks!
