What I always used to say is that if they were easy they would be selling eggs that colour at the supermarket and garage. The very fact you only see good dark eggs occasionally shows how difficult they are to breed.
But if anyone is any good at poultry and would take a serious interest there is a big unfulfilled market for quality stock. Now I have given up there is really only one other guy who even has the potential to produce them. I am hoping those folk who have taken my stock on will be able to keep the stain going, as I have to say it was what a Marans really should be. - A strong heavy bird laying a sensible quantity of lovely coloured large eggs
Also do join the Marans Club - it is in desperate need of dedicated new breeders and there is a network to funnel potential buyers through to good breeders
www.themaransclub.co.uk Its only £6 to join and they have a good year book (well I have to sya that as it me as does it

)
