It's a whole grain type feed and not a pellet or crumble?No corn in the feed. No soy. Grumbly Farms food. View attachment 3580937
If so, I highly recommend switching to a pelleted or a crumbled feed because whole grain type feeds give the bird an option to pick and choose which of the grains they want to eat, which can lead to them not getting a balanced diet.
For example, if they chose to eat mostly just the sunflower seeds and the grubs they would be getting a high fat diet....way too much fat.
