I am new to your group, but it looks like you guys have a lot of knowledge. This is my second attempt at hatching in an incubator. I had an old junky one last year and hatched only 11 of 48 eggs. Worse yet ... nine of them were roosters. Now I have a new Little Giant with the turners and the chicks seem to be growing well. I am trying to hatch some red sex linked chicks. I am on day 16 now, so will have to take them out of the turner soon. Am I supposed to have the red plugs in top of the incubator in or out at this point? The directions say to take them out, but it doesn't say when (beginning or end) and it never mentions putting them back in. I think they regulate the humidity. Would putting them back in make the humidity rise for the last few days or would it make my chicks suffocate? I'd appreciate any suggestions. Thanks!
