I can help you with that but zanna has some nice birds. I would try to fine an unrelated roo and work with her birds as much as you can. Hatch some pullets and then use her roo over the new pullets.I want some more marans eggs LOL but not in the hundreds LOLHome grown and shipped .... all get the same treatment. Just hatched 4/5 that made it to lockdown (6 were shipped). They were nice color too. No sanding. Sally sunshine hatched 24 i think from about 36 i shipped. I dont think she sanded them either. That was a few months ago maybe for new years day or soon after.dont shoot the messengerREALLY?????? I hatch hundreds of Marans a year and have never needed to sand an egg to get it to hatch. I do think you are just asking for trouble removing that natural barrier we all so value in reg eggs. I will rinse an egg i will not scrub it to remove the bloom why would you sand a marans? I dry incubate the same for all my eggs and have very very high hatch rates.....that is why i am on this thread....i need help....i have about 400 chicks under the age of 4 weeks....more hatching today too.....there is no hope for me I set 150everything more yesterday.you hatch local eggs though correct?
