So here is a question that might be stupid, but I just need to know. I have a staggered hatch going on. We are at the end of the 21st day with one set which hatched 9 babies out of 19 so far. But the other set which are on day 19 now I put in yesterday before the others hatched today. What I want to know is, when the babies hatch and the goo is stuck on the other eggs not due to hatch for another 2 days, do they become contaminated and then dont hatch?!? If this is true should I open the bator to wipe down the eggs and put in a new shelf liner??????? Please let me know, I hate having bad hatches!
