If you get them in the morning or afternoon, what I would do, is let them set until it gets dark. The first thing you want to do is candle them before you put them in the incubator. When you candle you want to look for loose air cells, these eggs can be put in the incubator but need to be with the large end up and not moved or turned for at least 5 days to let the air cell set completely...sometimes they do and sometimes they dont... You also want to look for cracks, sometimes you can not see the cracks just by looking at them. If you do see cracks, cover them with candle wax to close it back up unless it's leaking. If it's leaking there's no sense in keeping it... You kind of want to get them in right away just in case they have already started to develop. Sometimes on the trucks they are quit warm and the eggs will start the process so in order to save it you need to get it in the incubator.. Also when you candle you want to look for things floating around, usually if something is floating around in the egg then it got scrambled and will not develop...
