I was carefully planning out my eggs to arrive close to the same day. My ebay eggs came today! My others do not ship until Monday. I know they need to sit for a bit but how long? I don't want them out so long I loose viability. When should I start these and do I dare have 2 different hatching dates in the incubator? Incubator is up and running for the last two days so at least that is OK.
