I have 5 hens that lay either green, white, or orange/beige. My rooster cannot get to them. I found these 2 eggs the other day and cannot figure out what happened to them. They were fresh (probably 1 was just laid that day and the other the day before), not sitting out in the sun, one in the nesting box and the other in a corner of their coop with 2 other eggs. They have green but then they show the white and then the circles of the orange/beige. These are the only 2 I have seen. Everyone is very healthy and eating a healthy diet. Any ideas what happened here or if I should be concerned? Thank you.
