We're newbies at raising chickens. My daughter raised them as her 4-H project. We have a hen that has started laying lighter eggs. - see picture. We had a sick hen with a severe eye infection, and I thought it was her that way laying them. She died last week, and we've gotten three more light eggs. I've not noticed one hen acting funny, so I'm baffled. I'm afraid to eat them, for fear she is sick and I've thrown them out. Any ideas? The brown is the norm, and we get a lighter tan. We have 5 RI reds & 2 buff brahmas. You can see that they started spotted, then got lighter, and are now almost white.
