she has been sitting for about 3 weeks now on about 20 eggs. the other day i looked at it because she went to eat and swim and seen some are turning black/gray looking. are they bad?? she has been sitting like crazy, but im afraid they are bad b/c they look like the same color when i incubated some and then candled, and found out they were bad. i really dont want to mess with them, but i dont want her to waste her time either.Anybody else had the same experience??
