I had to buy a dozen RIR eggs this morning, not a big deal they were $2.00 for the dozen. I put 7 in my incubator (that is all this type holds) based on nothing else but trying to choose the lighter colored eggs to help with candling. I have left the other 5 in the carton in a closet and they should theoretically be OK for another 7 days, the eggs were taken off the nests for me this morning so they are fresh. My question is if I candle the eggs in the bator in 5-6 days and see some not developing I should be able to swap with some of my 5 leftovers. However if all candle good, you think the 5 left would be OK to eat or would they have to be in the fridge for that? Also, if you think I should not eat them, what about scrambling them up for my existing flock of egg layers?
