Ashem0: Come over to the May hatch, we can follow your incubation trials and tribulations there. I am sure my incubation experience was bad due to the fact the post service left my eggs out in -5 celsius for over 8 hours! I put 8 more in the incubator (Marans, Ameraucana, Welsummer and Barnevelder) and I only have 4 that are developing. Some are clear, 2 had blood rings. So I will keep my fingers crossed for your hatch for sure!!! Please post some pictures of your hatch!! BTW, the link was informative, thanks.Wow what a harrowing time it has been for the 3 of you with your Maran's incubation.
I have just put 6 in a bator this morning - French Wheaten Marans (the only type available here in Oz, very rare too) I have to say, that I am hoping for a more positive outcome than you all had. I said a prayer for each of my little brown babies as they went in. Cause it sounds like that's all I can do! Some things have to be left up to mother nature I guess.
It is the first time I have incubated and I know I didn't pick the easiest of breeds to start with. Apparently because of their very thick shell it can be harder for them to break out of, than white or tan shells. But of course if the egg isn't fertile to start with that's irrelevant.
This link is an interesting read on hatching Marans; http://www.darkbrowneggs.info/#/incubating-maran-eggs/4541610539
Better luck next time!
