goatkeepers, your humidity sounds fine, just perfect.
This is my FIRST hatch ever, I fear my temps were a touch too high.. I had 3 thermometers all reading something different... I kept the humidity low during incubation, and am having trouble getting it up now... I didn't learn to use my water trays well before I did this...
So.. I've actually been using a steamer to add humidity & warmth to the entire room they are in... I used an extra bedroom as the hatchery. So.. the room itself is pretty warm & moist, but inside the bator I'm still reading 63-71% depending on which hygrometer I look at..
I don't know... but just hang in there.. breeds, setting, incubation temps & humidity all play a role... this is early.. if it makes you feel any better, i'm actually starting to worry about mine because they are early...
