These eggs were all laid either Saturday night or Sunday morning. I weighed them - From left to right - 3.4 - from a barred rock 3.35 - from a barred rock 3.4 - from a buff orpington 3.75 - not sure but I think a RIR The odd 5th small looking egg is a normal large buff orpington egg for size comparison. I am trying to remember what they had to eat that was extra the three days prior. I know they had some oats, rice, yogurt and boss - along with some salad scraps and egg shells and some 15 grain bread. I wonder what combo set off this production in my girls.
