With no water right now the humidity is 20% I am trying to get the temp and humidity right before the eggs arrive, the temp is between 99.5 and 100 degrees. I have had a lower hatch rate with the Marans eggs than with lighter colored shells, all are shipped eggs. I hope I can finally get enough to hatch my own. Thanks for the adviceit is really humid here so hard to get it really low. I don't add any water in the summer and use stuff to absorb moisture andbcant get it under 40%. in the winter it hovers at 30%. the lower the better. I will add water if it reads LOW....but that is it.
