I have several roosters, light Brahmas and barred Rocks, that are turning a yellow color on their white feathers. What causes this and how can I prevent it from happening?

Do you have a lot of sunshine? It may be one of the causes. Then you have to keep them in the shade.

Yes, we have abundant sunshine. Not every rooster is displaying the yellowing though. Do you think it is reversible with time in a shady coop, or do I have to wait until the molt?

When the damage is done, it is irreversible. You have to wait until the molt. You can ask your hair dresser if he/she can bleach them. smile

We have something like 325 days a year of sunshine. For 6 months of the year, the temperature in the sun is in the hundreds. Rain is rare. White bird feathers don't turn yellow here. My birds roam free on the acreage.

I wonder if it's something your birds are being fed.

All are eating the feed store all purpose poultry feed; some corn, oats, and barley mix; pasture grass; and bugs as well as bananas and papayas too. All eat the same and some are yellowed but most aren't. After the molt all are white.

There are two genetic forms of white. I believe one is more susceptible to sunlight damage than the other, but I cannot remember which.

So if I want white feathers I shouldn't use the yellowed roosters for breeding? It is a genetic thing?

This can't be applied here. The birds involved are Columbian and barred, so there is neither dominant white nor recessive white involved. As far as I know, nobody made scientific studies if this is true at all (but I may be wrong), so it is probably only based on undocumented observations.

Maria, you can try to breed only from non-yellowing and tell us if this helps to solve the problem.

In my opinion their diet is too high in corn. I have seen this happen with barred Rocks in particular. When a diet is out of balance and there is excessive amounts of corn, the feathers tend to become brassy or yellow. I would try to remove any excess corn that you are adding to the feed. But as the others have said, the damage is done and you will have to wait for a molt.
