I have three chickens. A white leghorn, a buff orpington, and a barred rock. Obviously I get white eggs from my leghorn, but I started getting brown eggs and I don't know whos is whos. One of the eggs is a darker brown, barely, and a little smaller , the other one is slightly bigger and if you look close up you can see tiny white specks, adding to a lighter brown. If this helps, the first one is smoother and the second one was a little bumpy. This is my first year so any help will be appreciated!
