I made the mistake of forgetting to add water to the bator. Two days ago I candled and saw movement in a few, now I see very little movement in one egg. Did I make a fatal mistake? Crap.
I don't know if you made a fatal mistake or not. With you being on day 19 I would just go ahead and add water and wait. What has you're temp been at.
I asked about you're temp because it is different for a forced air and a still air. If it was two low they might be a little late at hatching. I just wanted to rule that out in case something does go wrong.
