Well I didn't expect to get "caught up" in the egg color for the Marans. LOL I just received eggs in a batch of purebred Marans and a batch of purebred Welsummers. Mainly interested in the Wellies for my son, but then also love our Ideal Cuckoo Marans hen we have as she is so sweet. Her eggs are not dark at all though but we still love her. Anyhow, I got these eggs today and two are a little lighter than the others. Still dark mind you but lighter. Is it true that at certain times of the season they do not lay them so dark? Are they affected by temperatures or light for egg color? And how do you get your hands on a chart for egg color rating? I do have to say I was surprised that the Welsummer eggs I received are very dark as well. I confess I haven't read all of the posts as this thread is getting long. However the pictures of some of the darker eggs I have seen you all post are similar to the ones I have in my bator. My chip reader is down or I would gladly post pics. Hopefully I will get that fixed here soon.
And one last question. If I breed this Ideal Marans into the new stock (assuming they hatch and I get a roo) will that mean her offsrping will have darker eggs?
