Has anyone else had trouble with feeding their birds Dumor? I've always fed my birds Dumor, but since having bantams they had many health issues that pointed towards a nutrition deficiency. Since I switched them to Purina I haven't had any more trouble. I've always supplemented calcium, grit, and some extra protein. I also give them fresh greens and occasionally nuts and seeds. Is there just something wrong with feeding bantams Dumor, or is it something beyond that?
