I'm getting a bit frustrated with my hatching.. I have a Hova Bator and I have done other hatches in the years with it. As long as there isn't any power outages, I get atleast a chick or two. I, unfortunately, have wood heat so my outside-incubator temp fluctuates, but I am home all day to watch it and adjust accordingly. This last hatch it went down a couple times overnight, but when day 19 came all eggs candled perfectly. It is now day 23 and one egg (the one right under the wafer) hatched last night. I have not removed the top and both trays were filled with water prior to lock down. I don't see any more cracks or hear any peeping, but plan to wait a couple more days just in case. I've tried to troubleshoot why they are getting this far and not hatching, but I can't seem to find my answer.... Any ideas?
