Today I got our second little egg can anyone tell me what is going on? The hen that laid this one today (brown egg) is 1 yr 4 mos. The hen that laid the green egg, age is unknown we call her grandma since she looks like an old hen. They eat well plenty of greens and laying pellets, oyster shell is available to them and they get some scratch and lots of water is available. The yolk in the green egg was smaller than an eraser head on a pencil. Any ideas?
