Seeds shouldn't be more than 50 % of the food, about 20 % of that should be millet seeds.
In the summer months my birds like to deal with collected "weeds". To mention just a few:
-
Rough bluegrass (Poa trivialis)
- Poverty and Soft brome (Bromus sterilis und Bromus hordeaceus)
- Common Velvet Grass (Holcus lanatus)
- Meadow foxtail (Alopecurus pratensis)
- Orchard grass (Dactylis glomerata)
