I had one chick hatching at 9 am 15 hours after pip. After a few hours when it dried up I took it out of the bator since he was really active rolling the other eggs around. Two more had piped. They hatched at 2 pm, also active. I have taken them out of the bator and they are doing fine. Six more eggs piped between 10 and 12 am. When I took the chicks out my husband helped me and the temp didn't change at all and humidity dripped 2% but not below 70%. The bator is getting very quiet. If I talk a long time with them I have an answer from one chick but it takes a while. Is it normal that they become quiet during long periods during hatching?
