Sound more like a giant cookie than bread (no leavening agent).
I use a bread machine and throw everything in it at night before I go to sleep and have freshly baked bread already cooled for the birds in the morning. You don't really need a specific recipe because the birds don't care if it comes out to dense, too dry, too moist or too anything, they like it anyway but to give you an idea, I use about 4 or 5 cups of 'dry' - for example, 2 cups of whole wheat flour, 1 cup of coarse corn meal, 1 cup of steel cut oats (rolled oats or even oatmeal) and 1/2 to 1 cup of whatever other flour catches my fancy at the time (could be spelt, could be rice, could be whatever -I don't use buckwheat since one of my parrots started plucking when I added it to the gloop -I don't know if it was coincidence or not but, just in case...). To this I add one envelope of dry yeast (yeast has nutritional value while baking powder does not), grated carrots, mashed sweet potatoes, maybe grated zucchini, orange or grape juice to moisten enough for kneading and whatever goodies I have handy -could be raisins, chopped dates, currants, chopped figs, sweet corn, sweet peas, naturally dried organic apple chips, etc. Set the machine to whole wheat bread, go to bed and in the morning, voila! fresh birdy bread! They love it and know the word 'Pan' for it and go crazy when I tell them they are having it
