Hey there! Thanks for visiting my thread. My budgies' food (seed mix from Petsmart) smells like rotting grapefruit. It's been like this for a while. Is the food harmful? I am not a very experienced owner, so I can't really tell you how my budgie is doing with the food. They don't seem super sick to me. But I'm not sure. Can anyone help me? You may reply asking for more information; I will provide as much info as possible.
