Sorry, but that is the craziest thing I have heard yet about hatching. LOL You must have read it on this site? There is a school of thought that you must let the eggs cool for 15 minutes each day and mist them with water. Not true. In fact, if you have a foam incubator and you are doing this, good luck. It is tough to regain heat and humidity levels in those units to begin with, opening them daily to cool the eggs is just not necessary. I am quite surprised you got such a good hatch with the whole degree fluctuation on your unit. Marans or Wellie eggs are no different than white or blue or green or any other shade of brown egg. Unless you are heating with a light and the heat comes from 'solar absorption' process, the color has nothing at all to do with it. The one thing that is true with Marans and Welsummer eggs, you need a REALLY bright light to see into them, which is how I discovered my quick-check way of candling eggs. A fertile eggs at 3-4 days will cast a shadow inside the eggs when candling from the bottom end, a clear egg is not fertile and casts no shadow. It beats trying to see veins through those dark brown eggs. As for thickness of shell, brown eggs are thicker, in my experience, than white, but what really determines thickness is the diet and health of the bird laying the egg.
Some of the crazy stuff I have read just floors me, which is why one should always double and triple check information especially on this site where there are so many over-night experts. I am not accusing anyone this is a general observation, but there are a lot of crazy things that go around that are propagated by people with little or no experience with chickens. If you want to know the scientific truth of how to hatch or what feed requirements are to maintain healthy birds and things like that, check out a Ag University website that goes into that stuff and can provide you with solid information. There are nuances to using different types of units, but if something sounds kind of "out there", it probably is.
I did read it on this site! Using the foam bator was seriously stressful. I felt I had to monitor it constantly which I did. If I decide to hatch more, I'll get a Brinsea. But I feel I have enough broody hens to go around the block a few times. And I was surprised my hatch rate was so good, too. I feel like I messed with it too much. I'm not good at leaving things alone
And I pretty much gave up seeing through them. I tried my best to mark the air cells at the end.
