today I got my first white egg, yippeh. I think it was Tobi as I have been seeing her in the last two weeks sitting in the nest boxes and making noise. The eggs are uniform in color, the circles must be from the plastic box. Note the two dog noses in the picture? 
3 days worth of eggs, I have been getting 3 brown eggs on most days, that's really not bad, the chickens are just 22 weeks old today
