Hi! I'm near Cedar Rapids and have 5 girls I purchased last year (you're right, they are so much fun! And they help keep the bugs down on our little hobby farm). I got 6 more this year (3 are the little bantams) what did you get?
The one with the white chest really has me puzzled. I think the little gold one (#1) might be a black tailed white Japanese bantam (but I'm not familiar with them- totally a guess)
