If you're sure your hygrometer is correct... the answer is no.My humidity in my incubator is On 41%....but theres no water in the tray. It's day 1 !! When I put water in it goes above 50%. Do i need water in the incubator if humidity is right without it ??
The eggs only care about the humidity, not if there is water in the tray.

Hope your hatch comes along well!
