I bought fresh whole corn at the farmers market. How do I serve it to my tiels to have higher chance for them not to be freaked out of a new "scary" thing?
My guess is that I serve it uncooked, or am I wrong?

My guys like raw kernels that have been cut off the cob. Some birds (especially the big parrots) like getting the whole cob, or a slice that's been cut from the cob in sort of a wheel shape. Cooked is OK too if your birds like it.
