How do u tell an internal pip. Also my hatch date is this saturday for my ducks. Most of them are rolling like crazy should i still turn them? Also my humidity is right at 65% and temp has been steady at 99.5 some spikes but within a degree or two. and last but not least i have one more newbie question.. What the max days i give my duck eggs with no piping or peeping. I have mostly mallard eggs with some cayuaga. This will be my second hatch and the egg health up to this point has been 100 percent better than the last one. thank you all for letting me ask such basic questions. I read alot of articles and each one sometimes varies drasticlly. Thanks a bunch
