We have six chickens -- 4 black sex-links, 1 ameraucana, and 1 wyandotte. They are all about 9 months old. When they started laying in July and August, I would get 4 brown eggs, 1 tan egg (from the wyandotte) and 1 cream colored egg from the Ameraucana. Then in October, the Ameraucana became very sick and stopped walking and eating and every day, I was positive she wouldn't survive until night. She obviously stopped laying and we got no more cream eggs. But she pulled through in the end and is just fine now. After a week or two indoors, I let her back out with the other chickens. One day soon after that, I found a weird half-cream - half-brown egg. Since then, I've found no more cream eggs. We get between 3-5 eggs per day (down from a late summer average of 5-6) Is it possible that the Ameraucana could now just lay tan or light brown eggs like the other chickens? Or did her illness knock out her reproductive system and she's not laying at all? If she's truly not laying at all she won't be long for this world, so I want to try to figure out whether her eggs could have changed color. Thanks in advance!
