Question about lockdown in a 1602 Hova-Bator

[Georgetownchick]

I have 11 eggs in this type of incubator. Never hatched eggs before. On the instruction sheet it says to fill the center trough for setting and both troughs for hatching. I have been filling the center trough only. Tonight is my lockdown night. When I went to fill troughs with water it looks like there are three troughs. A center one, then one around that one and the one on the outer edge. Do I fill all three? Should I have filled the very center one and the middle one for setting? Confused.

Are you monitoring your humidity with a hygrometer? The percentage of humidity should be 65% for lockdown. I have a Hovabator and I can achieve that with much less water.

Oh and days 1-18 - humidity should be 40-45%
