Hi All, I wonder how many of you are having problems with your hatching. I am talking sticky chicks/difficulty breaking out/leg and toe problems etc.? Sound familiar? I presume your temp(dry bulb) is at 97-98F (for ostrich/emu). BUT-the humidity levels that I have read and seen are crazy! Who on earth came up with dehumidifiers and suggested levels of 25-30% rel humidity? It's a wonder any chick is hatched at all!! Someone somewhere started this ridiculous idea not knowing a thing about the relationship of rel humidity and wet bulb reading. It is like putting your eggs in a clothes drier. Relative humidity should be 60% for setting and 70-75% hatching.(get a rel hum to wet bulb conversion chart if you use a wet bulb.) You need to get moisture in-NOT take it out! From what I have seen-many incubators are made by refrigeration people certainly the case in Australia,and they have no idea about incubation-only copy others. Get rid of the dehumidifier. Let me tell you what really happens in this dry incubator-All birds get their calcium for bones from the shell of the egg.The drier the environment-the harder is the shell and less calcium is released.I see chicks aplenty with toes taped.Hatching for the chick is also difficult,and the development has been impaired resulting in sticky weak chicks that have to be helped out and likely will soon die. In fact many breeders have resorted to humicribs to save them. Of course a proper diet is also essential for optimum fertility/hatchability and livability. I have a lifetime of experience in fully integrated commercial enterprises with particular emphasis on nutrition,and have seen 'miracle like' results.
