Very interesting. I will see what happens if Bernie ever graces me with an egg.for what it's worth, my experience with brown egg layers is that they're very variable, individually as well as qua breed. Welsummers and Penedesencas both supposedly produce a relatively dark brown egg, but Puffin lays a much darker one than the other two Pennies here, and all of them are a bit variable depending on whether they are at the beginning or end of a cycle, and what they ate recently (one sometimes makes a plum bloom), and other unknown influences too. I still haven't worked out why Janeka's eggs are sometimes speckled (spotted) and sometimes not. And the first eggs are not always reliable indicators of how they'll settle down, so however exciting it is when Bernie finally gets round to it, don't get too hung up on the colour, because it may change!
