So--now, I'm curious. My 18 wk old CL, Aretha, laid our/her first egg on Sunday. I got another egg today (Thursday). Same size, maybe slightly smaller, but a slightly different shade of blue. My next oldest are 16 wks old CL. Surely, there's not a possibility one of THEM laid the second egg--is there? Their combs and wattles don't look like they're ready yet.Are you sure it's just 1? The coloring on the eggs seems to be a few shades different which makes me think you have 2 laying...
