Hi folks; long time no post. I've been getting a run of eggs with mottle-looking yolks. Mom insists on throwing them out; I don't know enough about it to know if they're good, bad, or indifferent so I'm not arguing. She's the one doing the cooking; I just bring 'em in. I've asked her to get a picture next time she gets one, as the only times I've seen them, I've been on the way out the door and couldn't stop to play camera games. The best description I can give is to imagine an egg with bloodspots... then image that instead of red, those sports are orangy, just a little darker than the yolk. The ones I've seen don't vary much otherwise from other eggs. The yolk might not stand as tall, but other wise color and smell are similar, and the whites look fine. Any idea what's causing this? Is it really a problem or are the eggs just fine? The "Optimum Egg Quality" site page on mottled yolks doesn't seem to have anything that might apply other than worms (and I'm not seeing evidence of worms; nothing obvious in droppings, and if anything they're eating less food than usual lately, egg production has declined a bit, but I've got one who's broody and we had a run of hot days, then a run of cold, then I put the young 'uns in with them, so they have plenty to disrupt production anyway).
