I am a new poultry person and am considering the purchase of a Brinsea Octagon incubator. Given my lack of experience, I find myself wondering a lot about the role of humidity control in the process. One of the reasons for this is because I live in a very dry area and it is not uncommon for the relative humidity to be in the single digits or low teens. So, my question is this: Of the three Brinsea models available, the Eco, Advance and Advance EX what would you recommend for a first-time incubator dealing with low humidities and a full work schedule? I'd like to keep costs down, but if the Advance or Advance EX really does a much better job, then I'd rather make the investment. For now, I will use the incubator on chicken eggs. Thank you for your thoughts!
