I have no problems with Barnies. I feed them as I would any chicken. A chicken pellet with some cracked corn and I free range them during the day. Will try and post some photos of the eggs and chickens.
Why would you not keep a chicken if it lays light coloured eggs? The inside isnt reflected in the shell colour.
Why would it be labelled an expensive garden ornament?
I know the standard calls for dark brown eggs but I believe people think they should be as dark as Maran. They should be closer to half that shade though still med-dark brown. Not dark chocolate.
