Actually, most like boiled eggs and they are fine for them. As to the meat, Timber loves it. I do avoid giving him the processed meat like from the deli or packaged. It is heavy on salt and the nitrates aren't good for them. But when I cook a roast or other meat at home I give it to him and it's usually a hit. On that same note, he likes boiled or baked chicken wings. He will strip the marrow out of the bone (little cannibal
As to vegetables, just keep experimenting and offering them. You have to be inventive. Timber won't eat raw veggies in a bowl, but he will eat some (particularly green peas) when I hang them on a skewer in his cage. Same with broccoli and carrot. He will at least nibble when it is on the skewer. Cooked sweet potato is often one they will try. Try offering it on a spoon (that's the way Timber likes it). For some reason anything I hand feed him is much more acceptable than anything I put in the bowl. If none of that works, try sneaking veggies in via birdie bread or chop. There are stickies on both those I think. Don't just try one either. Sometimes they will start eating something they initially rejected.
