It's whole seed with shells, and they love it - usually pick it out first these days. What made me decide on the combo I'm using right now was just watching what they actually ate from the commercial scratch available. They left the milo for the local wild birds. I hate wasting money. I do feed wild birds, but most wild bird mixes actually have less milo and more millet. The oats they don't really love dry, but wet/fermented it's apparently delicious

They also love it when I have leftover oatmeal. Really, anything. I have given them ham bones with some meat left on them, turkey carcasses, ham and bean soup, whatever I have a little left of that isn't worth storing and not spoiled. They are like piranhas.
