Hi, I have some special Marans eggs on their way. Does anyone have some tips for incubating Marans eggs? I bought some from ebay a few months ago, with bad luck. One egg hatched, with a healthy and vigorous baby. When I cracked the other 10 eggs open on day 25, one had developed until about day ten, and the other nine all had scrambled and rotting yolks. Thanks for your help, Faith D. p.s. I have a Brinsea Eco 20.
