I have four 2-3mo. old girls (1 polish, 1 cochin, 1 maran, & 1 wyandotte) and the polish is hyperactive to say the least! She does not allow the other three to run or move fast - if they do she jumps on them. What is up with that? Is she just trying to establish dominance? As well, I have noticed that at dusk, it is posturing time. Not violent, but a lot of jumping, flapping, and approaching one another (in each other's face so to beak, I mean speak). Then they all go into the corner and sleep ontop of each other. I have never had chicken this young, so is that normal behavior?
