i am day 8 into the hatch. I bought some eggs from a local guy who said they where fertile eggs well only 6 out of 3 dozen are doing any good i trashed the bad ones. I also put in 2 dozen of my eggs and only 3 of them turned out to be bad so far. What should the humidity be at ? It is a air incubator that i built. The current humidity is at 49% and the temp is staying at 99.5. This is my first hatch and first time using a incubator. So i need a little help. Thanks for looking at this post.
