Its my first time to use my new hova bator 1388 which i shipped recently. I got 30 eggs, i set up my incubator and started the incubation periods. Two days after, i got another 10 eggs and added them to the incubator. Now i noticed that i should increase the humidity for the last 3 days, What can i do ? if i raised the humidity for the at day 18 of the 1st group off eggs, i will be raising it at the day 16 of the 1nd group. What is the best thing to do ? Thanks and waiting for your help reply guys !
