We have a new banty who just joined our flock. She's 9 weeks old & the 3 others are 5. She seems to keep them in line pretty well. She doesn't lead them around the yard - she keeps up the rear all the time. Do those of you who have mixed flocks (banties + medium-sized birds) find that the banties are not-so-large & in charge? Is this an age or a demeanor thing? Personally I'd love to see her be in charge - she's sweet, stays really close, and seems to "teach" the younger birds things.
