I just put my eggs in the bator, got the temp/humidity to stay at a safe spot so I decided to put them in. I'm not sure if the eggs will hatch, I got a dozen from someone who said they were left out in the coop during some really cold nights (probably in the 20s or so) and I took one from my D'Uccle that I just bought on Saturday to see if it'll hatch (my not even be fertilized). I figured these will be a good test run, lol.
