I just recieved my second batch of eggs. Out of the 1st I didnt get a single baby so I really want these to hatch. She told me some of these eggs were around 7 days old when shipped so I knew there was a risk. Then they got stuck in the mail for the weekend and I just recieved them today. My question is... since they are older eggs should I get them in the bator right away? What is the shortest amount of rest time I should give them?
