    Hello everyone,
    i have four red sex links hens. Two are facing their second molt this fall, and two will face their first molt this fall. Anyway, the older two have always laid very large (Goose sized eggs), dark dark eggs with orange yolks. the younger two are large egg layers (XL according to store bought eggs). they are consistent layers. But my question is the color of their shells and yolks have recently lightened up. Can you explain why? im not concerned about health issues, everyone is doing fine. except one of them just went broody ( yes, a rsl went broody....grrrr) . anyway, the discoloration has taken place this last two months or so. thanks for your help!!!!

    Some birds, (mostly pullets) go through a stage called bleaching. This is when they use their lighter colors in egg production.

    Egg color will lighten up as the season progresses, eggs get bigger which spreads the pigment further. Hens can become depleted over the season as well, especially high production hens. Things like stress can alter an eggs appearance, heat is considered a stressor so if you have been hotter that could be the cause, and some hens egg color changes over time. You can expect the darkest eggs at the beginning of the laying cycle and the end eggs will be lighter.

    Thank you very much, i didn't even consider the heat affecting color. My girls do like it cold, but we are in the 90's. Im sweating, so i can't imagine being covered in feathers! Thank you!
