How are all of you identifying which chicken is laying and what eggs each chicken lays. I have all brown egg layers, 4 buffs, 1 red sex link, 1 barred rock, and I have gotten three eggs. The first two came every other day and were about the same color, the third came the day after the second and was just a tinge darker. I can't tell if they are from the same chicken, or even which chicken any of them came from. Please give me any tips that you know.
