Hello all, I recently purchased some white Langshans and am curious as to what causes yellowing in white birds? I remember from when I raised white Giants, any corn even in the vicinity turned the feathers yellow. Dust-bathing wasn't that large of an issue with getting yellowed feathers but some birds yellowed worse than others. I've also heard it's the same as sun-damage except the feathers turn yellow instead of the brown color that black birds have when sun-damaged. So, my question is, is there anyone that can post photos of birds that have: sun-damaged corn-fed dirt-caused or genetic yellowing? If anyone has specific examples of each type, I would be grateful to see them! If you have a combination of these or know what caused the yellowing, please give me your ideas! Thank you for any help! Also, if you have any ideas as to keeping birds that tend to yellow that gorgeous bright white that is somewhat elusive to anything but a cotton ball, I'd love to hear them. ETA: I was going to make a separate post, but didn't want to take up more space than necessary. Does anyone know what causes marbling in the eyes? I was "told" that marbling is caused by worms. I've noticed that none of my birds have marbling, but the new whites do. Is this true? Either way, I've wormed them but would like to know if there is any truth behind it?
