I know many people wrote about this before, but i would like to hear everyone experiences with best feeds that brings the more yellow color on the spalding and green birds faces, my spalding birds had more yellow color on their faces back when i bought them 2 years ago, so i'm trying to bring this yellow color back. I also have green and spalding peachicks which i'm trying to add more yellow color on their faces. I have read the birds will need feeds that will produce more keratin in their bodies, so i listed all these kind of feeds to give to my birds: 1- Kelp meal(will only be in the peachicks feed not in the adults feed). 2- broccoli(once a week). 3-peanuts(once a week). 4- eggs(once a week). 5- Dry cat fish feed.(once a week). 6- beans(once a week). 7- Kale(once a week). Please let know about this plan.
