My girls are 17 weeks old, they are my first chickens. I inherited two banties that were already laying when the girls were 5 weeks. Today I went to check the coop and there was a small blue egg!! (I have 2 ee's) My Bantam EE lays small Green eggs, that are not shaped like this egg. Could the banty hen lafed my a different color egg? Or did one of my girls lay be a BLUE egg!! Egg in my hand. Blue Egg on top, the rest are green and white banty eggs. Blue Egg on bottom.
