Okay good. I keep hearing. Don't let the humidity get too high and then it happened. And this is my first hatch so I kinda freaked out.
That's for days 1-18. During lockdown my humidity is around 70. I have a remote display and when I see it says 80 I say yep, another one just hatched. When it says 90 I know 2 are in the process. As the chicks hatch & dry it drops back down to 70.
