That is totally me too! I wait a bit, but then I pop and look in all the eggs (about 10 hours after the last hatch).
I just did the pop and look in this morning on the set that was to hatch Monday... CLEARS!!!! So many clears!! I have decided that maybe it is do to lack of exercise... They are kinda cooped up to keep the eggs pure..... Anyway, after googling that is all that I could come up with... Dunno
The last chick.... Not hatched is WIERD.... I will have to google, and figure out what happened with that one.
I don't think that is a good study.... Spain is hot so will have lots more nasty stuff.
Don't get me wrong, I think filth is wonderful
There was a great study in Germany that showed that eating cow poop will reduce the risk of you getting allergies, asthma etc. much more than any other poop (horse, pig, and chicken)
