I have been using a forced air Styro Bator for three years now. Every year I have had multiple hatching with 80 - 90% hatch rate with very few problems. This year I decided to start hatching earlier so that the girl would lay by the summer. But.... Every hatch this year have gonna haywire during lock down. Every hatch the chicks stuck in there shells while zipping or gets gooey nastiness that all effects the chicks hatching on there own. It looks like the whites either get so sticky the chick can't move or the white completely dries them to the shell. But all the shell linings look good, not dried out or brown. I can't tell you how many I have intervened, almost all of them. Its been 4 different hatches with all the same results. After the first time this happened and reading I thought maybe because its winter and dryer outside I need my humidity higher. I always hatched at about 60-65% humidity. So the next three hatches I bumped up to about 70-80%. But this is not working. I also noticed this last hatch that my temp dropped to about 98. The bator says it was still 101 but my accurate thermometer I use was at 98. I slowly increased it back to 100. So I don't know if that could have added to this issue. But what to do? Need advice from veterans that have seen this issue and found a solution.
