I just finished (?) a Cream Legbar hatch from shipped eggs, actually they are on day 22 and still in the incubator. Out of 16 eggs only one hatched, they were packed wonderfully, appeared to have sustained no damage during shipping and the shipper said her hatch rate was 90 + percent. They were placed in a hovabator Genesis with auto egg turners set on their standard of 100 and per the back up thermometer they were 99.5, humidity I tried to keep between 25 - 40% and at lock down raised it to 70%. Now I have read several articles and am so confused about what to do with the air plugs - do I leave them in, take them out what?? I ead take them out at 10 days, take them out at lock down, take them out only if you need to drop humidity? I know there are a lot of experienced hatchers on here and hope I can get some guidance.
