I set my eggs on 05/23 at 5:10 am. Am I right in thinking that I take the turner out and kick up the humidity on Thurs 06/10 am? That would be day 18-right? Is that when I kick the humidity up and lock the bator down? Also, what do I do if the humidity drops (or raises) too much during the last 3 days? If I need to add water to keep humidity up, how do I do that without opening the bator? Also, when do I remove the vent plugs during the hatch-after all or some have hatched? I know these are probably dumb questions, but I am a 1st timer--sorry and thanks for ya'lls patience.
