My 3 hens are all doing well since I brought them home. 2 seem to be laying well, (it's only been about 4 days since I brought them home) the third has yet to lay any eggs yet. She is shy but seems to be the smartest one out of the bunch. They were all hatched last summer so they are all only just turning one. The eggs are blue and one almost has a green tint. Will they darken with age or will they always be this light?
