OK.... I haven't hatched anything since April of last year and I think I forgot how to. I am putting 18 eggs into lock-down right now. They are Marans and I was not able to candle them, so they all went into lock-down. I usually cut one of those mini plastic cups down (see pic below) and fill it along with both trays with water. I usually put something between the cup and the eggs so that none of the little chicks can get to it. This time I have no room to separate it. Do you think this is too dangerous. I mean.... can one of my chicks drown or do you think this is too small for them to drown? Also, if one of them knocks it over and the water falls on an unhatched egg, do you think the water would ruin the unhatched egg? Am I over analyzing this and stressing too much. Edited to state: I apologize pic looks so fuzzy. I took photo with my cell phone and my bedroom light gives kind of a yellowish light. Also, the eggs are not dirty. What you see is fog on the bator from the humidity.
