First hatch for me... I have 4 eggs left in the bator with large dark masses - 2 with movement and 2 I didn't see any. I am on day 24 (out of 26 to 28 for guineas). I put them in lockdown Thursday night because I needed to get in it the bator anyhow - they were supposed to lockdown Friday. One of the thermometers wasn't visible so I opened it up and moved one of the eggs. It was wet underneath - the one beside it was too. No moisture anywhere else on those eggs. A quick candling showed movement in one egg - neither of the two that were wet. I'm sure I could have spilled water somehow yesterday? Is that the only thing that could cause wet only on the underside?
