We set our eggs at 6:00 pm on Friday, April 30th. So would I count day 1 as May 1st? Then we should go into lockdown on Tues. morning then? That would be the 18th. It would be a little over eighteen days. Is that ok? Also, we kept our humidity up until now somewhere between 35-40%, as I read lower humidity is better for the first 18 days, what does everyone think? Then try to get it up to 60-70% for the last three days, or what??? Also they say not to open the incubator during the last 3 days, but we might have to add water, right? We have a Brinsea Octogon 40dx. Thank you... I know a lot of questions, but I am very nervous!!! Thanks!
