They look like they're getting enough food.

That home has some age on it, even then. The hand-hewn logs give that away. It was old enough to have reached the point where these old log homes were covered with clapboards to look more modern. I'm sure Mark Bowe and the "Barnwood Builders" would love to get their hands on this one, if it still survives.

Not certain about which one is "Mama", though I'm guessing it's the standing woman holding a baby.
This family makes me think of my Aunt Zella and Uncle Clark who (while living in a half dug-out near Kim, Colorado) had 16 (!) children by about the time this photo was taken, though some did not survive childhood.
It was a very different time back then (as we are routinely reminded on Shorpy).
