Question: I have been arguing with my friend about hatching eggs. We both had trouble hatching his Golden Cuckoo Marans eggs. When I tried, I noticed that the air sacs in his dark eggs were too small by lockdown. The air sacs in my regular brown, green and blue eggs were about right. So, my thoughts were that I needed to lower the humidity when hatching his eggs. I feel that the dark coating of color on his eggs is really thick and so needs less humidity at the beginning so that more moisture comes out of the egg and makes the air sac bigger. Am I thinking correctly? I am asking this because he said he contacted McMurrays and asked them about humidity for Marans eggs. He said they told him he should use high humidity. (55%) to start. To me, that would make less moisture come out of the egg during incubation, therefore having a smaller air sac.. And, that is what was wrong with my hatch (of his eggs). Any comments?
