I don't know, button quail chicks are pretty darn small. But yeah, ummm.. newly hatched house sparrows are smaller. Totally legal to harvest here but the challenge is that I usually don't discover a nest until I can hear the chicks. By that time they've grown quite a bit but are still about the same size as a quail chick.

The hard part is not falling in love with the food. They're so darn cute. For that reason I usually ask my supplier to freeze them for me before I pick them up.
