Hi, I'm incubating my first quail hatch (coturnix). The humidity has stayed between 51 and 58%, most often at 55%. Is this too low? I've been trying for 60% but it just isn't happening even with extra water added. I'm confused - I've read that 60% is the requirement but in the sticky at the top of this forum monarch23 says between 40 and 50 is just right. Please clarify. Thanks!
