Can you tell me more about a constant motion turner? I hatch at 5400 ft of elevation and while my own eggs do okay, shipped eggs I've all but given up on because of poor outcomes. I did have 10 of 12 shipped Cochin eggs hatch a year and a half ago, but I'm nearly certain it's because the post office messed up and got them here in 24 hours and I set them right away LOL. I will have to try the humidity modification you mentioned, never thought of doing that.Locked down a day early. Hatch should be on Wednesday. Of course it will be on a day I am running mom around to doctors and for tests 2.5 hours away from home. out of 15 eggs, 2 were removed on day 8 when I candled. Unlike most of you, I only candle at most twice with the last candling being done on lockdown. A lot of times I only candle on day 18 for shipped eggs. The less handling the better for my hatch results my records indicate as I hatch at high altitude. I also normally run humidity near 70% for teh first week then bring it down to around 50% until lockdown. I find my air cells are pretty close to where they need to be doing this. The first week I incubate shipped eggs pointy end down in a constant motion turner, then switch them to the Nurture Right for the last and I have found that no matter the outcome, my air cells have always returned to where they should be and as the vein web grows, it fixes the air cell in its proper place.
This hatch humidity has been a nightmare to keep constant and instead of refilling the ports once a day, it has been more like 5 or six times a day. I will be glad when this hatch is over.
