I live in western Colorado at about 4500 ft elevation. I've received 5 shipments of well packed eggs and have not gotten ONE to hatch!!!!!!!!!!!! The most common problem is that they make it to the day before lockdown and then fail! WHY?????? I know they need more oxygen so I'm only putting them in my forced air Hovabator and I'm trying to keep the humidity around 30%. I have NO problems with my own eggs. I had 2 Polish to go into lockdown today, I candled and one had failed since yesterday. I'm scared to even move the other into my LG still air with higher humidity, fearing that it'll suffocate! What should I do????
