I am so new to this - Ive been reading threads to get ready for my first hatch. We plan on driving to a farm this weekend to get a dozen eggs. My daughter and I are so excited - my DH thinks we are crazy! My question is do I need to prep before I bring home the eggs? I have the incubator and turner set up but not running - should I start it? I also do not think it came with a humidity gage should I get one and if so, where can I find one? Thanks in advance for any help!
