So, my Nurture Right 360 malfunctioned on day 22 which resulted in the death of a few of my babies. I took it back and exchanged it for a Brinsea Mini Advanced II. I believe I have it all set up correctly, however, there is no humidity read out. Per the video and manual, I filled half the center water holder. Is that good? Is that considered 55%? When day 18 comes, do I fill the second half? Is that 70%? Not having a read out on the humidity worries me. Does anyone have this incubator?
