I have some Barnevelders who are supposed to lay dark brown colored eggs. The color is coming off when I wash them. They aren't as dark as I thought they'd be in the first place and I try letting them "set" which helps some but not always or everywhere on the egg so I end up getting a mottled or smeared looking egg color which looks like I tried dying my eggs but didn't do a good job. If the pine bark sticks to the egg it marrs the color where it stuck. It doesn't hurt the internal quality of the egg but I sell them and they look down right messy. Has anyone else had this problem with dark brown egg layers? Is there anything I can do to help alleviate this problem?
