I feel like i’ve Posted in this forum a lot lately But i’ve Noticed some poop that is yellow instead of white. ( I don’t talk about my free range birds a lot, only really focusing on my show birds here. But I do have about 20 free range birds that live in an actual coop and not my garage area.) But there is a group of 6 or 7 cockerels of mixed breeds that have been hangin out in the garage around noon when it gets hot, and because it’s easier to see droppings I’ve also noticed that only these 6, who venture farther out into the yard farther than the others, have started having yellow in their poop instead of white. Is this something they are eating? They are about 6 months old, and are fed a mixture of scratch grains, layer pellets, cracked corn, and wild bird seed and have been being fed this since they were 3 months old (big enough to eat it). There aren’t any yellow flowers, besides dandelions in the yard, that they could be eating. We do have bulbs that haven't bloomed, and all my birds LOVE to dig them up . Any ideas?
