We raised a female house finch that was a tiny barely feathered baby from a crow on our roof. She bonded with us and loved us in her own way. She sang the songs of her people, hung out on my hat or mouse hand and slept, and stole our food and drink. She loved baths in any water container we held up and loved her toys and was just plain happy. I think if your Lil guy is already imprinted and likes people he'd be very happy with you and be a tiny fun addition to your flock.
