...when my son was in 6th grade, he brought home a baby house finch with only the beginnings of feathers..(like sparrows..noisy & mean)..well, we fed it cat food and kept it warm. I figured it would never make it, but I was wrong. The bird died about 2 weeks ago, after 7 years of chirping, sitting on us, pecking our eyebrows, laying un-fertile eggs, yelling for attention and generally keeping us entertained in its own belligerent way......you just never know.....
