hello everyone, I have a home made egg incubator and this is my first time incubating. I'm on the end of day 20 and there is still no internal or external pipping, and I'm starting to get worried. Has anyone ever dealt with this before? I'm not sure what I should do. The temperature has stayed around 99F to 102F,and the humidity the first 1-17 days was between 50-54% then after that 57-62%. Also I'm not sure how to refill the water? so far I have been spraying water with a spray bottle through the ventilation holes and that seems to be doing okay. I only put in 11 eggs and as of day 15 only 2 or 3 of them are showing signs of development. They look very dark inside and the air cell is very clear, but no veins. I am doing barred rock eggs which are brown, but early in the development stages ( day 7 candling) I could see no veins, just darkness. Though I think that they were developing at some point though because of the growing air cell. Anyone have any advice on this? Thanks!
